Regression in `podman run hello-world`

[apyrgio]

It seems that podman run hello-world within a krunvm was possible a few years back: #30.

This no longer seems to be the case for the following reasons:

[user@localhost src]# krunvm start archlinux bash
[root@archlinux src]# podman run --rm -it  hello-world
Error: netavark: create bridge: Netlink error: Operation not supported (os error 95)

and if we disable networking:

[root@archlinux src]# podman run --rm -it --network=none hello-world
Error: container create failed (no logs from conmon): conmon bytes "": readObjectStart: expect { or n, but found , error found in #0 byte of ...||..., bigger context ...||...
