# To populate the UUIDS value below, run the following command on a Nova api server to get list of VM UUIDs that are known to OpenStack:

# nova list --all-tenants | awk '{print $2;}' | grep -E '^[0-9a-f]+' | tr '\n' '|' | sed -r 's/\|$/\n/'

# Then paste in the results for UUIDS below OR define it in the environment before running this script.
