[CentOS] using KVM Virbr0 with bonded nics?

YOu will have to do it on the virbr side, if it does not pick it up
automatically.  If the bond is set to be your default route, it may just
"do the right thing".  More surprising things have happened...

Still working on a solution. Apparently the bond<n> files demand an 
ipaddress, thus there might have to be one for each and
every single ip coming into the computer...I guess you would have to do 
that anyway just like
eth0, eth0:0, eth0:1, etc.
I think I am going to try to just make a separate eth<n> for each ip, 
going to their respective bond<n> with the proper ipaddress
in them. Then use the bridge as normal, with each bond<n> calling a 
respective bridge.
Not sure how that works with multiple ips going to same machine (as in, 
can the bridge handle more than one ip, or can the machine
look for more than one bridge...?)

Then obviously, the VM would need to go through the whole process too. I 
can see no other way and there is no
information out there going over any of it...will post if it works.
(next step after figuring out lvm kvm storage issues.....wheee)
