[ovirt-users] LACP Bonding issue

[Derek Atkins]

For what it's worth I set up my bond0 manually on CentOS before installing
ovirt hosted engine and the ovirtmgmt bridge "took over" from bond0..  But
it appears to still be working.  At least I've not noticed links being
down, and "ifconfig" shows decent amount of traffic on both eno1 and eno2.

Maybe wipe, re-install, configure it manually, and then install ovirt?
