I have a feeling a better approch is cpompletely avoid the booting to 
east...  to transmorgify. This is a serialzed step and does not scale wel 
with larger number worker Qs. On Xeon Server with 32 cores it could take 30 
- 60 minutes. Think of 120(24 Worker Qs x 5) boot up and shutdown.

I feel a better approch is mount the qcow2 files and make the changes to
necessary files, /etc/hostname or systemd files, network configs, directly 
instead of booting.
