[libvirt-users] How to copy snapshots of a VM to the other computer.

Currently, I've tried to move qemu VM image to a new computer. So, I copied VM image files in /var/lib/libvirt/images, VM xml files in /etc/libvirt/qemu, VM snapshot files in /var/lib/libvirt/qemu/snapshot to the same places at the new computer. Everything is OK except snapshot!! When I use "qemu-img info" for the copied VM image, I can see the snapshot list in the result as shown below: root@doc-scheduler:/var/lib/libvirt/images# qemu-img info VM22.img image: VM22.img file format: qcow2 virtual size: 10G (10737418240 bytes) disk size: 1.7G cluster_size: 65536 Snapshot list: ID TAG VM SIZE DATE VM CLOCK 1 VM22_A 228M 2013-01-31 10:06:45 00:06:38.110 But, when I use "virsh snapshot-list " for the copied VM, the result is empty as follows: root@doc-scheduler:~# virsh snapshot-list VM22 Name Creation Time State ------------------------------------------------------------ and of course, I can't revert to the snapshot. Please let me know how I can copy my snapshots to the new machine. Thanks.
