Been sitting on list for a while ....

Obviously I think you know you have to update to top of tree

Would be nice to perhaps add a few intro comments to
qemuMigratePrepareDomain at least with respect to what the purpose is
and what "could" be done in the future in the code.  Looks like to me
it's now a shim to qemuProcessPrepareDomain to take care of any of those
"inconsistencies" between what can be supported in/on the new system
(perhaps could work in the opposite direction too ;-))... When I'm
reading code, I'm not necessarily looking at the commit message that
added which may have that information.

I think you could also update the commit message to point at the
previous code that was reverted to help understand the history.

ACK for the concept - looks like things are OK to me.
