I've been running 14 CentOS5 VMs with bridged over active-backup bonded 
interfaces (actually, over three sets of bonded interfaces) on a single 
Ubuntu 10.04-LTS server KVM host for a couple of years now. The only 
real issue I have had is that during a host reboot the 'thundering herd' 
trying to autostart simultaneously sometimes doesn't reliably start all 
14 VMs and I have to manually launch the one or two VMs that fail to 
launch.

Also, I had to roll my own shutdown script because for whatever reason 
Ubuntu 10.04 thinks shooting running VMs in the head during a shutdown 
is a better approach than waiting for them to properly shutdown on request.
