Darrel, i tend to agree with you. One of the reasons for choosing ovirt over i.e vmware is
fact you will benefit from the flexibility of linux in general. Besides the fact its
actually quite good and open source offcourse. The fact ovirt stops accepting custom net
setups is not the best feature perhaps for most. At least not for me.
Either way using the bond approach i am at least able to crack on. I know there is a lot
one can tailor by defining config options in /etc/ovirt-host-deploy however it feels like
its one of the more undocumented features. I tried a number of things but ended up with
errors i had scavenge my way through. I am happy for now. Ill keep my eye out on the list
to see if this particular issue will be taken up in the future.

> I?m having trouble with that plan and I?m not even trying to put the ovirtmgmt bridge
on an existing bond. I have a pre-existing gluster setup with gluster running on a bonded
interface. The ovirtmgmt should go on a different interface, but even that fails on the
bond with the ?torn down manually? statement. Haven?t had much time to do more
troubleshooting, but it?s rather annoying.
