That would make sense only when you are powered off, wouldn't it? Otherwise what's the point of disk snapshot with open transactions, buffers in mem, etc, without saving the state of the VM too?
I understand syncing virtual disk state with the OS cache is a quite challenge to a snapshot tool developers. However, it is a handy feature for the users just want to back up their data in the disks without stopping VM. As other virtualization solution support this feature, we should narrow the gap to attract more users to oVirt.
actually, live snapshot today is only supported for disks, without the RAM. I can not find the button to create a snapshot for disk only in engine 3.1 beta release. Are you talking about a undergoing project?
Thanks, michal

Hi,
no. the snapshot is for the entire vm and it's disks.

Hi,
I am testing oVirt engine 3.1 beta release 06-07. I tried "snapshots-->create" button for a VM and it looked like that the snapshot to be created was for both the running state of the system and the virtual disks. I am wondering if there is any way to create the snapshot only for the virtual disks of the VM in engine?
Do we have future plan to make snapshot for it's disks?
