If you did not see tables print out above then the vm names may be running
already. You will have to delete them to recreate them with different atttributes
or move them to a different zone.

Check ./vm_status.sh to wait until the status is RUNNING.

When the vm is ready, run vm_setup_slaves.sh to setup all created slaves.
