Ahh.  Well, I'm building xen-3.1.3-rc1 right now and I'll see how that goes.

Keir, have you seen this issue before? Where one cannot xm save/migrate a 32-bit domU on a 64-bit dom0? Or is this expected to work and just doesn't go well for me?

Just to make sure the patches aren't the cause of this new error

Kurt, Keir, everybody else... any ideas as to why "xm save" (and thus
"xm migrate") of 32-bit domU's does not work on 64-bit dom0's?  Has
anybody found this to be successful in the past?

The extent of the patches that Kurt posted indicate its pretty unlikely to
work without considerable code modification. I guess those patches aren't
quite fully baked yet, unfortunately, or haven't been written with your
precise case in mind.
