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.
