Eep. Sorry for (again) not being clear.
The origin would never be assigned to a domU. It would be created
only for the first instance of a given distribution and then left
alone. If anyone mounted or modified it, they would do so at their
own peril. This pristine image could then be used as an origin for
all consecutive images of that role/os/what-have-you.

Yeah. I would never recommend taking a snapshot of a running domU.
