Hi,
I've a small openstack installation running Victoria on Ubuntu 20 LTS.
After a update (not upgrade) of Ubuntu, I loose all network on all my instance.
On a instance console I got :

in the log of neutron-linuxbridge-agent.log it seem everything should work :

But I'm unable to ping any instance.
Any idea ?
