Hi Mike,
Please apply the following patch to cloudstack, and copy the file
agent/bindir/libvirtqemuhook.in to repace /etc/libvirt/hooks/qemu on your
hosts

Can you confirm that those bridges and bond devices exist prior to
attempting migration, and that the VMs are attached to them and work?
Perhaps a 'brctl show' and 'virsh dumpxml'. Those look like they should be
cloudstack-generated guest network bridges and libvirt is complaining they
don't exist
Everything as far as I can tell is working minus this migration. I have a
few virtual routers running on this machine and VMs, each environment
running on the box seems to be doing working just fine. The base mgmtbr0,
cloudbr0, cloudbr1 all come up at boot prior to CloudStack and are working.
Command output is below.
Also: the router seems to have been restarted and was allocated on the
machine I was trying to migrate it to. Trying to migrate it back resulted
in the same error message.
