Source information not showing for virsh domiflist causing problems with migrating VMs
...ve several long
running VMs running on an Ubuntu 14.10 host and for some reason I am
getting errors when trying to migrate them to another host. If I restart
the VM then the problem does not exist, however for various reasons that is
not an option with the remaining VMs.
root@comp001:~# /root/bin/vm_migrate.sh ws001 comp003
virsh migrate --live --persistent --tunneled --p2p --unsafe --domain ws001
--desturi qemu+tcp://comp003/system
error: internal error: No <source> 'bridge' attribute specified with
<interface type='bridge'/>
I have eventually figure out that the problem...
