Hi,
In my test installation of OpenStack, I see that too many tap/qvb/qvo
interfaces are still there - but I have too few running instances to use them
all.
It looks like:
root@nova02:~# virsh list --all
Id Name State
----------------------------------------------------
3 instance-00000002 running
5 instance-00000004 running
6 instance-00000005 running
7 instance-00000006 running
8 instance-00000007 running
root@nova02:~# ip a

inet6 fe80::fc16:3eff:fe19:bd01/64 scope link

Is it a common problem, that those interfaces are left behind after instance
was deleted - and how they should be deleted at first place?
Cheers,
NM
