Is using LVs for this over-thinking things? Creating a snapshot of a regular file which efficiently shares the backing disk is easy, and doesn't require root or special support: qemu-img create -f qcow2 -b original snapshot.qcow2 Then you can import this as a new guest in libvirt, again *without* needing root: virt-install --import --name snapshot \ --ram 1024 --disk path=snapshot.qcow2,format=qcow2 And in Fedora 20 we'll have virt-builder, which makes creating the original images quick too. (Not to mention virt-sysprep and all the other tools to manipulate disk images easily, without root) Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming blog: http://rwmj.wordpress.com Fedora now supports 80 OCaml packages (the OPEN alternative to F#) -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
