Russell Coker's recent post about duplicating a Xen domU talks about using LVM snapshots, laying out the steps involved in doing it manually. Reading it gave me a sense of deja vu: what he describes is exactly how Xim does its thing. In fact Xim has a "duplicate" command that takes an existing VM and makes a copy of it under a different name. It even takes care of modifying the config file to assign different IP and MAC addresses, although it doesn't yet introspect the VM image itself to alter the interface config.
It's about time I let people have a peek and tell me what a load of junk it is so I've just put it under the GPL and put a link to the SVN repo on the Xim page.
