[one-users] write changes using "save as" and qcow2

[Shankhadeep Shome]

No you don't have to change image to persistent, it wouldn't change the
running vm anyways. After the shutdown there are two more states, EPILOG
and DONE. EPILOG is reached after the VM is completely shutdown and
reported back, DONE is after the VM files are deleted from the system
datastore, you should see both steps in the vm log. Maybe you can post the
last few lines of the vm log, just go to /var/log/one/<vm#>.log on the
opennebula server and post the last 20 lines.
