Hi Ahmed It looks to me you didn't create the volume group nova-volumes: Try this: " # This creates a 1GB file to create volumes out of dd if=/dev/zero of=MY_FILE_PATH bs=100M count=10 losetup --show -f MY_FILE_PATH # replace /dev/loop0 below with whatever losetup returns # nova-volumes is the default for the --volume_group flag vgcreate nova-volumes /dev/loop0 " OTOH, I'd recommend you post this question on the Launchpad answers section.
