[libvirt-users] Non-persistent disk

Hi Libvirt team, I am trying to create a new domain from XML file by using libvirt. I want this new domain using non-persistent disk as its disk. Non-persistent disk means that when the domain is running, all the modification would not be written to disk file. So next time, when you boot VM from the same disk file, you would have a fresh disk. I check the website but I could not find anything about this. I wonder if libvirt support this function. FYI, if I use KVM, I can use command "qemu-kvm -snapshot" to boot a VM on non-persistent disk. If I use VMware, I can set disk type to Independ-disk, non-persistent.
