I certainly am not someone who knows that code well, so can't help
with that. But I (or more accurately Diana) can reliably replicate
live migrate on HVM and qemu-upstream DM causing (a) ACPI entries
to disappear from xenstore and (b) walltime to fail to advance in
the migrated domain until the walltime is manually set (stuck
clock).

Is this likely to be related?

Diana's threads are here (second and third being most relevant):
