[PVE-User] WG: Making a VM non persistent

Hi Laurent 

If you use a filebased VM, try qcow2. You can have an overlay img over a base image. But you have to create it every time you start the VM so you need some scripting:

qemu-img create -b base-disk.img -f qcow2 disk.ovl
(check qemu docu)

Simple way would be allways copying base img over working img before starting the VM...

Regards, Holger

The goal is some kiosk like remote VM.
