Hi Cris,
Both behaviours are possible, depending on your storage model.
With a non-shared storage, you need to successfully shutdown your VM,
otherwise changes are not transferred back.
In a shared storage scenario, you are using the 'master' image directly
(opennebula creates a symlink)
We are
I'm curious as to when changes to an image are written to disc. A fellow
on irc the other day seemed to think that if your kernel paniced you
would lose any changes since the vm was started, and it would revert
back to that state of reboot. But from reading the docs it doesn't seem
like they would
