Re: [libvirt] [PATCH 00/12] Unbreak vm's backed by RBD disks

After recent refactors, starting a VM whose disk is backed by RBD storage would fail as the parser for the backing file specification string was not implemented in the metadata crawler. Reuse qemu's parser to do this and fix a few things around.
