Part of the cleanup is ensuring the target node is moved _back_ to the freepool. This should theoretically "heal" cases where the node wasn't in the freepool but also wasn't in some lease aggregate. However, this call to Nova's API refers to the freepool aggregate by its name, which is not supported here: the ID must be used[1]. This caused this operation to fail and raise a NotFound, confusingly (because Nova couldn't find an aggregate with ID='freepool' for example.)

To fix, this removes much of the custom logic in the BlazarContext and keeps only the two important bits: 1. A stack of contexts is maintained to allow for nested operations w/ different sets of credentials 2. The service_catalog is preserved. It's unclear if this is really needed long-term, but some code still relies on it. Also unclear why the oslo context doesn't include this when parsing headers. Support for multiple domains is included as part of this changeset. Before, it was assumed that all users (admins and project users) were part of the default domain. .. NOTE:: This updates the default policy to use a project placeholder as %(project)s. Previously, it was %(project_id)s. Any overrides will still work, as this change is backwards compatible.

The Blazar manager can first run the start_lease event of the second lease. This event would fail since the end_lease event of the first lease would still be UNDONE, and the compute hosts in common would still be in the aggregate associated with the first lease, instead of being in the freepool. This patch changes event execution code so that events are executed concurrently if possible, with the following constraints: - events are executed strictly in order, i.e. events are started only after all previous events have completed - when events are at the same time, we first execute before_end_lease events (unless there is a start_lease at the same time), then end_lease events, followed by start_lease events, ensuring the bug described above does not happen. Finally, we run any before_end_lease which had a corresponding start_lease event at the same time. It also has the side effect of providing better stack traces for event execution failures, since we call wait() on all GreenThread objects.

An Alembic migration script is included to add `deleted` and `deleted_at` columns to all tables. Compute hosts and extra capabilities are not given soft delete capabilities: compute hosts primary keys match Nova compute node IDs, which could create conflicts if a host is deleted and re-created. Accordingly, the Alembic migration script removes the foreign key relationship between computehost_allocations and computehosts, since compute hosts can be deleted from the database while soft deleted allocations are kept.

Wed, 12 Feb 2020 16:06:01 -0600 Subject: [PATCH 025/362] 200 HTTP Response for DELETE (not 204) After Train upgrade, lease deletiong began failing because of how python-requests/HAProxy was handling an empty response body in a 204 (NO CONTENT) response. Easy fix was to respond with an empty dictionary in a 200 response.

11:26:49 -0500 Subject: [PATCH 028/362] Add Usage Enforcement Filters (#33) Implements filter based architexture for usage enforcement. Two filters are included initially. MaxReservationsLengthFilter allows operators to define the maximum reservation length of a lease in seconds. The ExternalServiceFilter sends lease values and allocation candidates to an external HTTP service where policies can be defined. All filters must be enabled in blazar.conf in an enforcement group. When ending a lease, the allocations currently associated with the lease/reservation are sent to the enforcement layers to perform processing. This works fine when deleting a lease, but when a lease naturally ends, that is, when the current time is > the lease's recorded end time, the allocation lookup returns 0 results because we have a filter on the time of the lease/reservation by default, which starts from datetime.now. This is really not what we want to do when explicitly filtering on a lease/reservation, so this updates the generic query function to not apply this filtering in this case. It turns out, it was possible for usage enforcement's on_end hook to run multiple times if the first reservation teardown failed. In this circumstance, the end_lease event would be IN_PROGRESS but the reservations would be in an error state. The code only checks if any reservation is DELETED before trying to run on_end again. To fix this, only try to run on_end if we detected that there was an UNDONE end_lease event; that's the only time in which we'll actually be responsible for running this logic. This also updates the delete logic to be a bit more consistent with the internal way we track states. It is not enough to check dates, because it could be that Blazar never got around to actually starting the leases; we should be checking events. This also makes the logic a bit easier to understand. NOTE:: This also fixes something which has probably been a bug for a very long time. The 'end' event was never set to 'DONE' when a lease was terminated early by the user (via a deletion.)

constraints can be implemented by operators via +custom usage enforcement filters or an external service. + +Description +=========== + +Usage enforcement filters are called on lease_create, lease_update and on_end +operations. The filters check for whether or not lease values or allocation +criteria passes admin defined thresholds. There are currently two filters +provided out-of-the-box. The MaxReservationLengthFilter restricts the length +of a user leases. The ExternalServiceFilter calls a third-party service +for implementing policies using token-based authentication and url provided +in blazar.conf. + +Options +======= + +All filters are a subclass of BaseFilter class located in +blazar/enforcement/filter/base_filter.py.

However, in the case of physical hosts, if not enough candidates existed, no error would be raised at this point, leading to the entire transaction of a lease create/update failing halfway through, but critically after already sending the information to the enforcement service, which never gets notified that the lease failed to create/update. Allocations should be checked _before_ sending to the enforcment service to make sure that there are enough in the system to satisfy the request. This updates the allocation_candidates function to do just that. It does not update the _matching_hosts helper function, as that is used elsewhere and is assumed to not throw an exception, letting the caller decide what to do based on the number of host_ids it returns.

However, if the user who created the lease is deactivated or is not a member of the project anymore, operations modifying the lease and lease events fail to execute with an AuthorizationFailure exception. This is because the trust object is not valid anymore due to the change of permissions for the trustor. This patch removes the context from all notification messages and stops using trusts except for the initial lease creation. This allows project members and OpenStack admins to manage the lease after the creator user is disabled or has been removed from the project, as well as lease events to run properly.

So it may cause allocation overcharge when the balance service filter runs before the max_reservation_length filter. For example, if someone tries to extend the lease two days prior to the end time, the project will be charged with the encumbered SUs but then failed on extending the lease. ---

To fix, this removes much of the custom logic in the BlazarContext and keeps only the two important bits: 1. A stack of contexts is maintained to allow for nested operations w/ different sets of credentials 2. The service_catalog is preserved. It's unclear if this is really needed long-term, but some code still relies on it. Also unclear why the oslo context doesn't include this when parsing headers. Support for multiple domains is included as part of this changeset. Before, it was assumed that all users (admins and project users) were part of the default domain. .. NOTE:: This updates the default policy to use a project placeholder as %(project)s. Previously, it was %(project_id)s. Any overrides will still work, as this change is backwards compatible.

The Blazar manager can first run the start_lease event of the second lease. This event would fail since the end_lease event of the first lease would still be UNDONE, and the compute hosts in common would still be in the aggregate associated with the first lease, instead of being in the freepool. This patch changes event execution code so that events are executed concurrently if possible, with the following constraints: - events are executed strictly in order, i.e. events are started only after all previous events have completed - when events are at the same time, we first execute before_end_lease events (unless there is a start_lease at the same time), then end_lease events, followed by start_lease events, ensuring the bug described above does not happen. Finally, we run any before_end_lease which had a corresponding start_lease event at the same time. It also has the side effect of providing better stack traces for event execution failures, since we call wait() on all GreenThread objects.

An Alembic migration script is included to add `deleted` and `deleted_at` columns to all tables. Compute hosts and extra capabilities are not given soft delete capabilities: compute hosts primary keys match Nova compute node IDs, which could create conflicts if a host is deleted and re-created. Accordingly, the Alembic migration script removes the foreign key relationship between computehost_allocations and computehosts, since compute hosts can be deleted from the database while soft deleted allocations are kept.

Date: Mon, 10 Aug 2020 11:26:49 -0500 Subject: [PATCH 102/362] Add Usage Enforcement Filters (#33) Implements filter based architexture for usage enforcement. Two filters are included initially. MaxReservationsLengthFilter allows operators to define the maximum reservation length of a lease in seconds. The ExternalServiceFilter sends lease values and allocation candidates to an external HTTP service where policies can be defined. All filters must be enabled in blazar.conf in an enforcement group. When ending a lease, the allocations currently associated with the lease/reservation are sent to the enforcement layers to perform processing. This works fine when deleting a lease, but when a lease naturally ends, that is, when the current time is > the lease's recorded end time, the allocation lookup returns 0 results because we have a filter on the time of the lease/reservation by default, which starts from datetime.now. This is really not what we want to do when explicitly filtering on a lease/reservation, so this updates the generic query function to not apply this filtering in this case. It turns out, it was possible for usage enforcement's on_end hook to run multiple times if the first reservation teardown failed. In this circumstance, the end_lease event would be IN_PROGRESS but the reservations would be in an error state. The code only checks if any reservation is DELETED before trying to run on_end again. To fix this, only try to run on_end if we detected that there was an UNDONE end_lease event; that's the only time in which we'll actually be responsible for running this logic. This also updates the delete logic to be a bit more consistent with the internal way we track states. It is not enough to check dates, because it could be that Blazar never got around to actually starting the leases; we should be checking events. This also makes the logic a bit easier to understand. NOTE:: This also fixes something which has probably been a bug for a very long time. The 'end' event was never set to 'DONE' when a lease was terminated early by the user (via a deletion.)

Existing restrictions apply; it is not possible to remove a capability in use explicitly by an active or pending reservation.

However, in the case of physical hosts, if not enough candidates existed, no error would be raised at this point, leading to the entire transaction of a lease create/update failing halfway through, but critically after already sending the information to the enforcement service, which never gets notified that the lease failed to create/update. Allocations should be checked _before_ sending to the enforcment service to make sure that there are enough in the system to satisfy the request. This updates the allocation_candidates function to do just that. It does not update the _matching_hosts helper function, as that is used elsewhere and is assumed to not throw an exception, letting the caller decide what to do based on the number of host_ids it returns.

However, if the user who created the lease is deactivated or is not a member of the project anymore, operations modifying the lease and lease events fail to execute with an AuthorizationFailure exception. This is because the trust object is not valid anymore due to the change of permissions for the trustor. This patch removes the context from all notification messages and stops using trusts except for the initial lease creation. This allows project members and OpenStack admins to manage the lease after the creator user is disabled or has been removed from the project, as well as lease events to run properly.

torn-down host aggregates (#91) * Add check for improperly torn-down host aggregates When a reservation ends, the hosts reserved by it are supposed to be moved from the reservation's aggregate into the freepool aggregate. Sometimes, this doesn't happen correctly, so there is additional code added to the host monitor to clean up these errors periodically. * Iterate hosts and move hosts to freepool based on reservation status create a new db utils method to collect host's non pending reservation details By iterating through hosts and getting the most recent non "pending" reservation on the host if the reservation is active, then everythig is alright - the host must be in the right aggregate. but if it is in deleted or error state, then we need to move the host to freepool * Addressing review comments - added current time by 5 minuts to skip leases about to start removed adding to recovered hosts and failed hosts Added test cases * Better log messages for host cleanup * db returns are dicts, modify code to use dicts instead for hosts and reservations along with few code fixes * rename method and filter out active reservations from DB --- blazar/db/sqlalchemy/utils.py | 43 +++++++++++- blazar/db/utils.py | 4 ++ blazar/plugins/oshosts/host_plugin.py | 40 +++++++++++ .../oshosts/test_physical_host_plugin.py | 69 ++++++++++++++++--- 4 files changed, 146 insertions(+), 10 deletions(-) diff --git a/blazar/db/sqlalchemy/utils.py b/blazar/db/sqlalchemy/utils.py index c89e0a6dc..e7bea1a2c 100644 --- a/blazar/db/sqlalchemy/utils.py +++ b/blazar/db/sqlalchemy/utils.py @@ -15,13 +15,14 @@ # under the License. import sys -

mostly tried to make it similar to host monitor plugin * include neutron client wrapper * Clean FIPs if the reservation tagged in neutron is deleted or in error state process FIPs in parallel through threads Todo: Add test cases * Catch exception when the tag does not have blazar reservation * Unit tests for the floatingip cleanup * add monitor plugin opts * change the Db filter to get all the reservations of the list of floating ips * change set_reservable in fip plugin to update the reservable flag add floatingip_update db utils method * Make changes to appropriate cases to return the polled FIPs to recovered or failed * Get the most recent FIP reservation to skip it when cleaning up * unittests fix * Some log messages to understand what is going on * optimize query to use inner joins and better logging * use list_floatingips instead of show_floatingip as show might not be working * Use UTC time and better logging statements with test cases Use UTC time to filter reservations Raise FIP not found in neutron wrapper show_floatinip method. Use appropriate logging debug/warning statements recover FIP if FIP does not have tags in neutron New test cases for floatingip plugin monitor * remove unwanted and condition * Add dry run flag for so floating IPs are not deleted in neutron * Use innter join for getting floating ip reservations by FIP id * COnsider the case when the reservation tag from neutron is not found in blazar DB * Use explicit Exception catch when FIP is not found in neutron Do not add to recoved list when the FIP is already in a good state. append fip to failed if the FIP cannot be deleted from neutron * Rename the config opt for polling monitor dry run --- blazar/db/api.py | 12 ++ blazar/db/sqlalchemy/api.py | 16 ++ blazar/db/sqlalchemy/utils.py | 63 ++++++ blazar/db/utils.py | 9 + .../plugins/floatingips/floatingip_plugin.py | 119 ++++++++++- blazar/plugins/monitor.py | 2 +- blazar/plugins/oshosts/host_plugin.py | 2 +- .../floatingips/test_floatingip_plugin.py | 191 +++++++++++++++++- .../oshosts/test_physical_host_plugin.py | 4 +- blazar/utils/openstack/neutron.py | 20 ++ 10 files changed, 428 insertions(+), 10 deletions(-) diff --git a/blazar/db/api.py b/blazar/db/api.py index 2e24be00f..bc98fbf87 100644 --- a/blazar/db/api.py +++ b/blazar/db/api.py @@ -520,11 +520,23 @@ def reservable_fip_get_all_by_queries(queries): return IMPL.reservable_fip_get_all_by_queries(queries) +@to_dict +def unreservable_fip_get_all_by_queries(queries): + """Returns unreservable floating IPs filtered by an array of queries.""" + return IMPL.unreservable_fip_get_all_by_queries(queries) + + def floatingip_destroy(floatingip_id): """Delete specific floating ip."""

20 Nov 2023 13:36:35 -0600 Subject: [PATCH 196/362] Disabled field in compute host (#97) * Add disabled field in ComputeHost model This can be used by admins to specify that a host is disabled for maintainance and that marks that blazar monitor should not touch or alter this host's health while it is disabled (True). THis helps admins to create a lease on the host while it is non reservable and host monitor not changing the status back to reservble - True * 'disabled' field to use in host plugin and admins can create lease when host is non reservable When disabled key is present in extra capabilities handle it by setting it or unsetting it based on the value for the key When disabled field is set to True for a host, the host also changes its reservable status to False. Disabled key can only be set by an admin An admin can create a lease on a host that is non reservable * Add disabled flag alembic migration file * Use the policy.enforce to check if the blazar context is a an admin from keystone * notification callback to use set_reservable method Fix tests that call matching hosts as users, so is_admin should return False New tests for updating disabled field new test for setting reservable True by monitor when disabled is True / False * Remove line in migration auto generated by alembic addressing PR comments change log warn to log debug if a host is disabled and admin is trying to set host reservable --- ...a379ff6ba3_add_disabled_in_compute_host.py | 47 +++++++ blazar/db/sqlalchemy/models.py | 2 + blazar/plugins/oshosts/host_plugin.py | 48 ++++++-

networks in neutron Iterate through each blazar network to find the networks that are not in 'active' or 'pending' reservation (maybe they are stuck in a lease) Tear down such networks in neutron which are not supposed to be in a user's project. Detach the network's subnets from the router. Delete the subnet(s) Delete the network * returns the recent network's reservation which is not in pending status and start_date of the reservation is less than current date * Montor plugin for Network resources With poll_resources() to teardown neutron networks while blazar's reservation/lease is in error/deleted state * unittests for network plugin poll_resources * Include monitor plugin in Network plugin * Remove the log info message that might break the method when network_curr_reservation is None. The message serves not much purpose and may also flood the logs Change-Id: If0f953256f049b6980ebfeeb9585761e3222e47c --- blazar/db/sqlalchemy/utils.py | 38 ++++ blazar/db/utils.py | 4 + blazar/plugins/networks/network_plugin.py | 116 +++++++++++- .../plugins/networks/test_network_plugin.py | 175 ++++++++++++++++++ 4 files changed, 332 insertions(+), 1 deletion(-) diff --git a/blazar/db/sqlalchemy/utils.py b/blazar/db/sqlalchemy/utils.py index ee2ebf021..7799d4311 100644 --- a/blazar/db/sqlalchemy/utils.py +++ b/blazar/db/sqlalchemy/utils.py @@ -289,6 +289,44 @@ def get_reservation_allocations_by_network_ids(network_ids, start_date, return reservations +def get_most_recent_reservation_info_by_network_id(network_id): + """returns the recent network reservation which not in + pending status and start_date of the reservation is less than current date + + Args: + network_id (): network id -

Two new API endpoints are added for hosts, ``/properties`` and ``/properties/``, which allow for listing available properties, and updating a property respectively. Properties can be listed with detail, showing possible values and visibility. Admins can list public and private properties. A new database table is added ``resource_properties``, which stores property names and resource types. Resource specific property tables (e.g. ``computehost_extra_capabilities``) entries store a foreign key to ``resource_properties``, rather than the capability name.

To fix, this removes much of the custom logic in the BlazarContext and keeps only the two important bits: 1. A stack of contexts is maintained to allow for nested operations w/ different sets of credentials 2. The service_catalog is preserved. It's unclear if this is really needed long-term, but some code still relies on it. Also unclear why the oslo context doesn't include this when parsing headers. Support for multiple domains is included as part of this changeset. Before, it was assumed that all users (admins and project users) were part of the default domain.

From 7addfa57e85221c8e4ffc71610a3170032c7cf5e Mon Sep 17 00:00:00 2001 From: Pierre Riteau Date: Wed, 8 Aug 2018 12:46:28 +0200 Subject: [PATCH 213/362] Prevent conflicting events from running concurrently If two leases have compute hosts in common, and the second lease starts exactly when the first lease ends, there is the possibility of a race. The Blazar manager can first run the start_lease event of the second lease. This event would fail since the end_lease event of the first lease would still be UNDONE, and the compute hosts in common would still be in the aggregate associated with the first lease, instead of being in the freepool. This patch changes event execution code so that events are executed concurrently if possible, with the following constraints: - events are executed strictly in order, i.e. events are started only after all previous events have completed - when events are at the same time, we first execute before_end_lease events (unless there is a start_lease at the same time), then end_lease events, followed by start_lease events, ensuring the bug described above does not happen. Finally, we run any before_end_lease which had a corresponding start_lease event at the same time. It also has the side effect of providing better stack traces for event execution failures, since we call wait() on all GreenThread objects.

Glossary of terms ----------------- -**Reservation** is an allocation of certain cloud resource (Nova instance, Cinder -volume, compute host, etc.) to a particular project. Speaking about virtual -reservations, we may have not only simple, solid ones (like already mentioned -instances and volumes), but also complex ones - like Heat stacks and Savanna -clusters. Reservation is characterized by status, resource type, identifier -and lease it belongs to. +**Reservation** is an allocation of cloud resources to a particular project. +Main properties of a reservation are its status, resource type, identifier and +the lease it belongs to. **Lease** is a negotiation agreement between the provider (Blazar, using OpenStack resources) and the consumer (user) where the former agrees to make some kind of -resources (both virtual and physical) available to the latter, based on a set of -lease terms presented by the consumer. Here lease may be described as a contract -between user and reservation service about cloud resources to be provided right -now or later. Technically speaking, lease is a group of reservations granted to -a particular project upon request. Lease is characterized by start time, end -time, set of individual reservations and associated events. - -**Event** is simply something that may happen to a lease. In most simple case, event -might describe lease start and lease end. Also it might be a notification to user -(e.g. about soon lease expiration) and some extra actions. - -Rationale ---------- - -Blazar is created to: - -* manage cloud resources not only right now, but also in the future; -* have dedicated resources for a certain amount of time; -* prepare for the peak loads and perform capacity planning; -* optimize energy consumption. - -Lease types (concepts) ----------------------- - -* **Immediate reservation**. Resources are provisioned immediately (like VM - boot or moving host to reserved user aggregate) or not at all. If request can - be fulfilled, lease is created and **success** status is returned. Lease - should be marked as **active** or **to_be_started**. Otherwise (if - request resource cannot be provisioned right now) failure status for this - request should be returned. -* **Reservation with retries**. Mostly looks like previous variant, but in case - of failure, user may want to have several (configurable number) retries to - process lease creation action. In this case request will be processed till - that will be possible to create lease but not more than set in configuration - file number of times. -* **Best-effort reservation**. Also might have place if lease creation request - cannot be fulfilled immediately. Best-effort mechanism starts something like - scavenger hunt trying to find resources for reservations. For compute hosts - reservation that makes much sense, because in case there are instances - belonging to other project on eligible hosts, and without them there will be - possible to reserve these hosts, Blazar may start instances migration. - This operation can be timely and fairly complex and so different strategies - may be applied depending on heuristic factors such as the number, type and - state of the instances to be migrated. Also Blazar should assert that there - are at least enough potential candidates for the migration prior to starting - the actual migration. If Blazar decides to start migration, it returns - **success** state and marks lease as **in_progress**, otherwise - - **failure**. If this 'hunting' ends successfully before configurable - timeout has passed, lease should be marked as **active**, otherwise its - status is set to **timedout**. -* **Delayed resource acquiring** or **scheduled reservation**. In this - reservation type, lease is created successfully if Blazar thinks there will - be enough resources to process provisioning later (otherwise this request - returns **failure** status). Lease is marked as **inactive** till all - resources will be actually provisioned. That works pretty nice and - predictable speaking about compute hosts reservation (because hosts as - resources are got not from common cloud pool, but from admin defined pool). - So it is possible for Blazar to predict these physical resources usage and use - that information during lease creation. If we speak about virtual reservations, - here situation is more complicated, because all resources are got from common - cloud resources pool, and Blazar cannot guarantee there will be enough - resources to provision them. In this failure case lease state will be marked - as **error** with appropriate explanation. \ No newline at end of file +cloud resources available to the latter, based on a set of lease terms presented +by the consumer.

Previously, this process involved making two large-volume API calls to fetch all hosts and allocations in Blazar, which resulted in delays and negatively impacted downstream implementations. To streamline this process and improve efficiency, a new API endpoint, `reservation/v1/leases//nodes`, has been introduced to Blazar leases. This endpoint provides the Blazar host IDs and hypervisor hostnames associated with the specified lease ID. By offering this functionality, operators and TMs can now obtain information about the nodes allocated to a lease with a single api call, significantly reducing the time required. Additionally, this change aims to enhance the loading speed of the lease details page in Horizon, thereby improving the overall user experience. Change-Id: I9271ceb1afd7057305bcccce5052a4824e9fe652 * Add new blazar api endpoint for networks and devices in lease Change-Id: Ib5bbdc305a52f884991213513583225ff4b2092a * Rename nodes_in_lease to

The first issue is fixed by only deallocating on success, or when the user specifies `force`. The second issue is fixed by never reallocating to an unreservable host, since this behavior is never desired. Additionally, reallocation is made easier with `reallocate_to` param, which will try to move the allocations to this host.

However, leases are created in a trust context, and the generation of that context drops roles. Blazar policy enforcement checks for the "admin" role to verify admin-ness, so this means the admin exceptions don't work. This change gets the role names from the trust, pass it through, and verify that the "is_admin" enforcement check passes in a unit-test. Note: create_ctx_from_trust currently looks up values from the current request context `ctx`, the keystone session of the trust `session`, and the session's keystone auth_ref. For consistency, we should probably get everything except request_id and global_request_id from the auth_ref, just in case roles, usernames, or anything else changes betwen trust creation and the lease action being taken. --- blazar/tests/utils/test_trusts.py | 33 +++++++++++++++++++++++++++++-- blazar/utils/trusts.py | 7 ++++--- 2 files changed, 35 insertions(+), 5 deletions(-) diff --git a/blazar/tests/utils/test_trusts.py b/blazar/tests/utils/test_trusts.py index 74e6aebb0..049d8c25e 100644 --- a/blazar/tests/utils/test_trusts.py +++ b/blazar/tests/utils/test_trusts.py @@ -19,6 +19,7 @@ from oslo_config import fixture as conf_fixture from blazar import context +from blazar import policy from blazar import tests from blazar.utils.openstack import base from blazar.utils.openstack import keystone @@ -63,14 +64,12 @@ def test_create_ctx_from_trust(self): 'auth_token': self.client().session.get_token(), 'domain': None, 'global_request_id': self.context.current().global_request_id, - 'is_admin': False, 'is_admin_project': True, 'project': self.client().session.get_project_id(), 'project_domain': None, 'read_only': False, 'request_id': ctx.request_id, 'resource_uuid': None, - 'roles': [], 'service_catalog': ctx.service_catalog, 'show_deleted': False, 'system_scope': None, @@ -78,6 +77,36 @@ def test_create_ctx_from_trust(self): 'user_domain': None} self.assertDictContainsSubset(fake_ctx_dict, ctx.to_dict()) + def test_create_ctx_from_trust_preserves_admin(self): + """Regression: trust context must preserve admin roles. + + When an admin creates a lease, the manager wraps execution in + create_ctx_from_trust.

This involves running `hosts_query.all()` which auto joins to computehost_extra_capabilities via `lazy=joined`. This caused the DB to return the entire table of all hosts and all capabilities, no matter what the query was. This whole-table fetch happens once per extra capability referenced, so it gets progressively more expensive as queries are added (gpus>4, arch=amd64,...). Even in the single-query case, with ~300 hosts the time to load results from the db into python dominated, leading to 100% cpu usage at 1 req/s.

However, nova hypervisors may be identified by hypervisor uuid, the hostname of the compute service for that hypervisor (host), or the hostname of the hypervisor itself (hypervisor_hostname). For virtualized nova deployments, host==hypervisor_hostname, but for Ironic backed hosts, many ironic nodes share a single compute service. Nova's api for hypervisors.search with servers=true will return servers for ALL hypervisors sharing a given compute service, rather than the specific one queried. We have carried a patch in Nova to fall back to matching by hypervisor_hostname as well, that is brittle. Since this is the only place in blazar consuming this particular api edge case, we can just do the lookup in two steps. First look up the nova hypervisor by id or hypervisor_hostname, and then look up servers using Nova's servers.list API, which explicitly supports filtering by hypervisor_hostname via the `node` keyword. If we don't need to preserve the "raise on 0 or >1 hosts found" behavior, the call to hypervisors.search could be dropped, simplifying the logic further. --- blazar/tests/utils/openstack/test_nova.py | 51 ++++++++++++++++++++--- blazar/utils/openstack/nova.py | 22 +++++----- 2 files changed, 56 insertions(+), 17 deletions(-) diff --git a/blazar/tests/utils/openstack/test_nova.py b/blazar/tests/utils/openstack/test_nova.py index fee1e906a..5f51ef8a5 100644 --- a/blazar/tests/utils/openstack/test_nova.py +++ b/blazar/tests/utils/openstack/test_nova.py @@ -21,6 +21,7 @@ from novaclient import exceptions as nova_exceptions from novaclient.v2 import availability_zones from novaclient.v2 import hypervisors +from novaclient.v2 import servers from oslo_config import cfg from oslo_config import fixture @@ -426,6 +427,8 @@ def get(cls, host): def search(cls, host, servers=False): if host == 'multiple': return [cls.FakeHost, cls.FakeHost] + if host == cls.FakeHost.hypervisor_hostname: + return [cls.FakeHost] if host == cls.FakeHost.service['host']: return [cls.FakeHost] else: @@ -445,6 +448,17 @@ def expected(cls): 'local_gb': cls.FakeHost.local_gb} +class FakeNovaServers(object): + + @classmethod + def list(cls, search_opts): + host = FakeNovaHypervisors.FakeHost + node = search_opts.get("node") + if node == host.hypervisor_hostname: + return host.servers + return [] + + class FakeAvailabilityZones(object): class FakeAZ1(object): @@ -487,6 +501,9 @@ def setUp(self): availability_zones.AvailabilityZoneManager, 'list') self.availability_zones.side_effect = FakeAvailabilityZones.list + self.servers_list = self.patch(servers.ServerManager, 'list') + self.servers_list.side_effect = FakeNovaServers.list + def test_get_host_details_with_host_id(self): host = self.inventory.get_host_details('1') expected = FakeNovaHypervisors.expected() @@ -529,24 +546,48 @@ def test_get_host_details_without_az(self): self.assertEqual(expected, host) def test_get_servers_per_host(self): -

When we ported the device plugin feature forward from train into 2023.1, (in 7386403), we reverted upstream's fix for instance reservation affinity being nullable. This adds an alembic migration to revert our bad commit. It may be handy to keep the migration in the repo even after a future fixup/squash, to ensure old versions of the DB can be updated successfully.

2001 From: John Garbutt Date: Mon, 29 Apr 2024 16:06:14 +0100 Subject: [PATCH 336/362] Implement allocation_candidates for flavor-based reservation This adds the flavor.instance plugin, where users request a reservation similar to: openstack reservation lease create test --reservation \ resource_type=flavor:instance,amount=2,\ flavor_id='e26a4241-b83d-4516-8e0e-8ce2665d1966' This uses lots of ideas from the existing instance reservation plugin, and where possible leans on some of the existing logic, currently only filter_hosts_by_reservation. The plugin is not currently usable. There are follow-on patches that implement reserve_resource and then finally update_reservation.

We are able to re-use the on_start and on_end implementation from the instance plugin, along with its cleanup_resources implementation. However, the flavors created for each reservation are different, because we copy the details from the source flavor, then add the Blazar-specific resource requests on top. This allows users to make use of pinned CPUs, huge pages, and simple PCI device requests and vGPUs. We do not support all flavor options, and these flavors will be rejected.
