> 3. Have some "template" image that gets copied when a VM is created. The copy should be persistent.

> Is there a way to do it? Non-persistent images behave almost like option 3, but accidentally shutting down a VM would mean data loss.

> We have quite a few VMs, but they all are used as real servers would be - all have different data (no scaleout) and none can be deleted easily.
