Thanks for the bug report -- but you're missing a lot of important
information to help us figure out what's going wrong.  You need to let
us know what version of Xen you're running, attach all the relevant
config files, and include the relevant console output.

So to begin with -- just to understand -- if you do a simple save /
restore, does that work?

Also, if you just do a save (without pausing), and then restore with
the alternate VM config, does that work?

Thanks,
 -George
