[ovirt-users] Re: Sparse VMs from Templates - Storage issues

If your vm is temporary and you like to drop the data written while the vm is running, you could use a temporary disk based on the template. This is called a "transient disk" in vdsm.

Arik, maybe you remember how transient disks are used in engine? Do we have an API to run a VM once, dropping the changes to the disk done while the VM was running?

I think that's how stateless VMs work
