[PVE-User] mixed linux bridges and openvswitch

[David Lawley]

Reading more on OVS, which I'm no means of any kind of expert, it would 
appear that promox still has it in use even for standard default linux 
interfaces and bridges.

And OVS stores its interfaces in /etc/openvswitch/conf.db

So guessing the db needs to be purged/flushed.

yea,nay?
