[libvirt] [PATCH] storage backend rbd: Do not prefix rbd: on volume names.
We used to prefix 'rbd:' to volume names, this is not necessary. Qemu takes RBD devices in this way, like: qemu -drive rbd:pool/image When attaching a network disk like RBD to a guest we however do not use this prefix. Currently you can't map a RBD volume name directly to a domain without removing the prefix.

ACK good to remove this redundancy Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
