Closing as this seems to have been the cause of a bad OVS version,
please re-open with more info if necessary.

Title:
you can end up in a state where qvo* interfaces aren't owned by ovs
which results in a dangling connection

Bug description:
While upgrading to rocky, we ended up with a broken openvswitch
infrastructure and moved back to the old openvswitch.
We ended up with new machines working, old machines didn't and it took
a while to realize that we had qvo* interfaces that not only wasn't
plugged but also wasn't owned by ovs-system - basically the virtual
equivalent of forgetting to plug in the cable ;)
This was quickly addressed by running this bash-ism on all nodes:
for x in `ip a |grep qvo |grep @qvb |grep -v ovs-system | awk '{ print $2 '}`
; do y=${x%%"@"*} && ip link delete $y ; done ; docker restart nova_compute
However, nova could pretty easily sanity check this =)
