[one-users] onevm data saving.

[Chris Cullen]

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 behave any differently than a physical machine in that
regard. I assume he was getting confused with non-persistent images, but
want to ask anyway.
