Yes. Old VMs are trashed with the bogus address reproted by the buggy
Vdsm. Can someone from engine supply a script to clear all device
addresses from the VM database table?
you can use this line (assuming engine as db and user), make sure only 'bad' vms
return:
psql -U engine -d engine -c "select distinct vm_name from vm_static, vm_device where
vm_guid=vm_id and device='cdrom' and address ilike '%pci%';"
if so, you can run this to clear the address field for them, so they could run again:
psql -U engine -d engine -c "update vm_device set address='' where
device='cdrom' and address ilike '%pci%';"

It seems like an unrelated failure. I do not know what's blocking
migration traffic. Could you see if libvirtd.log and qemu logs at source
and destinaiton have clues?
