Were able to fix the issue? Do we need to update
agent/bindir/libvirtqemuhook.in with Wei’s fix?
I can confirm the below patch fixes the issue I was having. Thank you
for the help in getting this resolved.
Forgive the delay on my response, work got crazy and I had to drop
testing for awhile.

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

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.
