[CentOS] using KVM Virbr0 with bonded nics?

Interested in bonding my 2 on board nics along with my add on card NIC 
for a total of 3.

How would this work with the virtual machines?
My eths/IPs ---> bond0, bond0:1, etc --->  ?   ----> virbr0,virbr0:1
(each machine to have own IP address, one machine may have some virtual 
sites needing more than one ip,
so multiple ips added to mix..)

add something to the bond0 file, or just leave it alone and mess with 
the virbr0 files?
I heard something about network manager not liking bonding and bridging...
anyone do this kind of thing?
