What does this say? virsh domblklist webdev That is the name of the disk where you are creating the snapshot. The --diskspec line needs two pieces of information: a designation for the current file being snapshotted (either the absolute path you used in your xml, or the shorthand name like 'vda' - valid names are found by the domblklist command); and the name of the new file to create the snapshot as. The fact that your error message complains about "no disk named '/tools/vm/images/webdev.img'" says that you probably didn't spell the file the same as it was named in the XML; seeing the domblklist command will make it clear what name you should be using instead. For the blockpull command, the same usage applies - you name the disk by its path (but note that you just changed the path as a result of the snapshot-create-as command; as another domblklist would prove) or by its device name, such as vda. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
