For full-blown pair-bonding, trunked VLAN's, and KVM bridges, you want
my old notes at
https://wikis.uit.tufts.edu/confluence/display/TUSKpub/Configure+Pair+Bonding,+VLANs,+and+Bridges+for+KVM+Hypervisor.

Just dial back on any features you don't need in your environment. And
rip all NetworkManager based components kicking and screaming the !@#$
out of any KVM server, it is *NOT* your friend.

      sudo yum remove *NetworkManager*
