[PVE-User] implementing openvswitch

[Sten Aus]

GOT IT!

I changed my interface names not to mix them up with linux bridges (as 
linux bridge was used by all of the VM-s, not just this particular 
proxmox host).

So, before i had (linux bridge) interfaces: vmbr10, vmbr15 and so on.
After, I had implemented ovs, I change them to OVSIntPorts called 
"backnet", "proxmox" and tagged to VLAN. But I just wanted to check - 
and now I've renamed all my interfaces with the same names they were 
used by Linux bridge and cluster is green! :)

Only thing - if anyone could speculate/help here:
If I manage to change all my nodes to ovs, can I rename interfaces then? 
Or is it more like "once you go vmbr10, you never go back"?
