Actually, although not intended (and was not tested), KVM's migration capability enables save/restore of non-qcow images. I used it to debug the migration code. Please look at the bottom of http://kvm.qumranet.com/kvmwiki/Migration ("savevm/loadvm to an external state file"). BTW, my little trick also works for "live" savevm/loadvm (kids don't try this at home). Hope that helps, Uri.
