To clarify my thinking on this a little more: I think it would be good to be
able to move PCI devices between domains in a reasonably straightforward way.
This would be something like the PCI hotplug for IBM's dynamic LPAR, which is
already supported by Linux.
The eventual goal being that you can reassign PCI devices "hotplug-style" (it
would look like a hotplug to the pcifront kernel) at runtime, with the user
interface providing appropriate safety checks / "do you really want this?"
dialogs, according to the level of confidence of the user.
Cheers,
Mark
