The primary question is - why is what we have not enough for you?
In particular I would expect that the call from arch_set_info_guest()
(for vCPU 0) should do what you want. Or wait, this is covering PV
only. So yes, with the description change I would then withdraw my
NACK - apparently no-one really used the shared info wall clock
time in a HVM guest so far (or it going wrong post-resume wasn't
noticed).

It was. Olaf posted a patch that would re-init the shared page for PVHVM guest

(for kexec to work) and it stopped migration on 32-bit guest doing migration.

Olaf and me never got enough time to actually dig in this to figure out why it was

busted :-(
