As in, when I leave on a Friday afternoon, start a script to clone the guest and auto start the live guest? Sounds more like you are interested in snapshots than actually cloning your guest, where you could resume execution from the point of the snapshot. And with external snapshots, it is indeed possible to automate the periodic capture of a snapshot of a running guest; where we still lack polish is the steps for reverting back to the state in a saved snapshot (it's doable, but requires effort outside of a simple libvirt API call). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
