from what i get it is a problem with libvirt, using a bridge that is going through a bond....on the same machine. It must be rather detailed to fix and only a few people seem to use that route. (like you and me)
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.
I used to see the same for RHEL5-based kvm-servers, but haven't seen this with any RHEL6-based servers that I would recommend for kvm installs now.
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.
I also tend to favour shutdown/reboots for kvm guests instead of suspend/resume...
