When a RBD volume has snapshots it can not be removed.
This patch introduces a new flag to force volume removal, VIR_STORAGE_VOL_DELETE_FORCED.
With this flag any existing snapshots will be removed prior to removing the volume.
No existing mechanism in libvirt allowed us to pass such information, so that's why a new flag was introduced.

Long term I could imagine there will be a number of reasons why it might be forbidden to delete a volume by default. It would be nice to selectively override these reasons. FORCED is quite a generic name for a specific action. So how about naming it VOL_DELETE_WITH_SNAPSHOTS Regards, 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 :|
