Public bug reported:
while developing https://review.opendev.org/#/c/689861
i observed that test_rebuild_server_with_network_affinity
https://review.opendev.org/#/c/689861/8/nova/tests/functional/libvirt/test_numa_servers.py@838
asserted that rebuild would fail after the numa policy required by the numa
aware vswitch
feature was violated. that behaviour was due to the fact that numa affinity was
not checked
as part of interface attach.
As such it was possible to violate the numa constraints and that would only
become apparent if you performed a rebuild with a new image which would fail in
the numa topology filter. ideally nova should prevent the numa constraints from
being violated on attach by rejecting the request.
