Jan, as we were solving this with Keir on the list I was unable to save
the HVM guest properly and reverting your c/s 21615 helped and with your
patch reverted it was working fine. Any idea why there were so type
failures for all the pages of HVM guest?
Not really, and I think you will need to find out by instrumenting the
hypercall implementation (XEN_DOMCTL_getpageframeinfo{2,3}) -
really, type failures should only happen for grant frames and I/O
memory pages (as you can see in the code, for the function to
report XTAB either the MFN must be invalid, must be a Xen frame,
or it must be impossible to obtain a reference to the page - all of
which shouldn't hold for the majority of a HVM guest's pages).
Michal, is it possible you are running new tools against a slightly older
hypervisor? The tools changes had a corresponding, non-version-checked,
modification to a hypercall. Without running the modified hypervisor, HVM
save would indeed behave very oddly!

Keir, I don't think so since the hypervisor datetime in /boot is the
same like for kernel and tools.
