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.
Well, it remains something to doublecheck at least. There's no good reason
that HVM save should work okay for everyone else and only fail so miserably
for you.

I don't know but I'll investigate it further but it's working with the patch 21615 patch reverted. Maybe something's wrong with my test setup. Some further investigation is necessary.
