Description
To avoid downtime while creating disk snaphots for VM's with ceph backed disk images it would be nice to have "live disk snapshot" (just like qcow2 drivers).

The problem behind this is either make virsh-snapshot-create support ceph; or force the KVM process to reopen the file descriptors of the virtual disk images. The latter shoul work through a virsh suspend + virsh disk-detach + ceph sanp + virsh disk-attach + virsh resume. This implies almost 0 downtime but the detach/attach operations of the root disks does not work throufh libvirt. Using qemu commands directly works but we rather wait for a libvirt solution either to reopen disks or native support.
