As you'd observed from the start, I suspect we need to drop the 'format=raw' from the command. Please add the following to the disk definition in your .xml file (i.e. virsh edit a1.6-q2.log):
<driver name='qemu' type='qcow2'/> So the whole disk definition will probably look like: <disk type="file" device="disk"> <source file="/var/kvm/a1.6-q2.img"/> <driver name='qemu' type='qcow2'/> <target dev="hda" bus="ide"/> </disk> -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. https://bugs.launchpad.net/bugs/691609 Title: Cannot migrate a VM from Ubuntu 9.04 to Ubuntu 10.04.1 LTS -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
