Hm, well I just saved/restored a 750MB PV guest and a 750MB HVM guest okay
with xen-unstable tip. However I think the above type-checking code may only
have been introduced for HVM guests as of Jan Beulich's recent changeset
21615. If your guest is an HVM guest, perhaps this changeset is to blame? I
would suggest reverting it and re-testing. I've cc'ed Jan in case he can
comment on the info you've given.
