First issue with fencing is solved per an earlier reply.
Second issue has also been solved earlier the way you outlined but I'm
wondering why oVirt can't use br0 as the ovirtmgmt interface instead?
What specific settings on br0 does it NOT like? Is there any provision
or flexibility to allow for custom defined bridges with oVirt?
I stumbled upon this page:
https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/
and tried it but oVirt would have none of it.
After I let oVirt setup it's own bridges, I can see the settings it used
(below) but wondering what *specific* settings in the network scripts
does it not like?
Would like to know what we can and can't touch in the config files if we
need to tweak the setup in higher level environments.
Cheers,
Tom
