Before proceeding for running the script please associate the vg file with a loop device with following command with root losetup /dev/loop2 /opt/stack/data/stack-volumes-backing-file Please use rejoin-stack.sh script located at your devstack installation directory or /opt/stack/devstack Best Regards, Swapnil Kulkarni swapnilkulkarni2...@gmail.com On Wed, Aug 21, 2013 at 12:37 PM, Batsayan Das wrote: Hi, I launch the openstack by running stack.sh as mentioned in http://devstack.org/guides/single-machine.html I created some images and instances in devstack using dashboard.

The thread http://www.mail-archive.com/openstack@lists.launchpad.net/msg08453.html says to use the switch --start_guests_on_host_boot --resume_guests_state_on_host_boot.
