[ovirt-users] ovirtmgmt manual bridge cannot be used in ovirt 4.0

[Charles Kozler]

What I've been doing since oVirt 4 is just configuring one NIC manually
when I provision the server (eg: eth0, em1, etc) and then let oVirt do the
bridge setup. Once the engine is up I login to the UI and I use it to bond
the NICs in whatever fashion I need (LACP or active-backup). Any time I
tried to configure ovirtmgmt manually it seemed to "annoy" the
hosted-engine --deploy script
