[libvirt-users] Clone disk image common ancestry/branching.

[Mestnik, Michael J - Eagan, MN - Contractor]

Hello,
  I was wondering if it was possible to support or easily extent libvirt to perform steps like the following when cloning:
# Any existing VMs must be paused or better.
ln $currentimg backing-store.img
qemu-img create -o backing-store.img $currentimg.tmp
qemu-img create -o backing-store.img $newimg
# Get any existing VM using $currentimg.tmp
mv $currentimg.tmp $currentimg

The idea being to create branches of an installs ancestry rather than simply duplicating the install.

Cheers.
