A number of hypervisors have a mode in which changes made to storage are not persisted across a reboot of the VM. qemu uses the -snapshot flag; VMware refers to this functionality as non-persistent disk[1]. Is this functionality something that is interesting to libvirt?
yes I think this is an important use case, it allows for example a rather trivial and safe implementation of things like open kiosk you may find in public places (or implement a scratch environment allowing the kids to play without much risk for a more personal/private use :-) !)
but is this the 'right' place to be doing this? It adds complexity Wouldn't it be simpler simply to make a working copy of a gold image in known state and start the copy? -- We follow that approach here -- Russ herrold
