[PATCH] x86/hvm: fix corrupt ACPI PM-Timer during live migration
The value of ACPI PM-Timer may be broken on save unless the timer mode
is delay_for_missed_ticks.
With other timer modes, vcpu->arch.hvm_vcpu.guest_time is always zero
and the adjustment from its value is wrong.
This patch fixes the saved value of ACPI PM-Timer:
- don''t adjust the PM-Timer if vcpu->arch.hvm_vcpu.guest_time is zero.
- consolidate calculations of PM-Timer to one...

Questions about fast clock in 64-bit linux hvm
...are updates to timer modes for different HVM guest
OSes. There isn''t any documentation anywhere, but I tracked down the
"timer_mode" xm domain config variable, and found the explanations of the
different values in xen/include/public/hvm/params.h. It looks like the
options are delay_for_missed_ticks (default, 0), no_delay_for_missed_ticks
(1), no_missed_ticks_pending (2) and one_missed_tick_pending (3). I tested
0 and 1 so far. I saw good results on one domain that hadn''t had much skew
in the first place, but the second one I tested was still a second fast
soon after I created it....
