Comment 1 for bug 620027

You can pass in a flag for a different storage device -->
./nova-volume --nodaemon --verbose --storage_dev=/dev/loop0
or in /etc/nova/nova-volume.conf:
--storage_dev=/dev/loop0

Also, if you just make sure that the volume group already exists, it will
work. The group should be called 'nova-volumes'. You can also specify a
different volume group name with a flag
--volume_group=vgfoo
