[ovirt-users] workflow suggestion for the creating and destroying the VMs?

[Arman Khalatyan]

thanks,the downscaling is important for me,
 i was testing something like:
 1) clone from actual vm(super slow,even if it is 20GB OS, needs more
investigation,nfs is bottle neck)
2) start it with dhcp,
3) somehow find the ip
4) sync parameters between running vm and new vm.

looks that everything might be possible with the python sdk...

are there some examples or tutorials with cloudinitscripts?
