[one-users] save changes in persistent VM disk without shutdown

[knawnd at gmail.com]

Hello all!

I wonder if there is any way to save changes made in persistent VM disk without shutting down that 
VM? The 'onevm stop' command saves persistent VM disk in /var/lib/one/datastore/0/<VMID> on the 
front-end but not in /var/lib/one/datastores/1/ where all registered in datastore VM images are kept.
'onevm saveas' command is not allowed for persistent VM disk.
So in order to save changes made in persistent VM disk (what can be treated as making backup) these 
VM has to be shut down and another VM has to be  created e.g. by executing 'onetemplate instantiate' 
command what resets accounting and history and not preserving assigned resourced.

Best regards,
Nikolay.
