[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

Guest time and TSCs since changeset 17716
...et 17716 provides monotonically increasing guest time for HVM domains, by using the per-domain pl_time structure. hvm_get_guest_time and hvm_set_guest_time were changed to use this. Previously, the guest time was stored directly in the TSC offset fields of the vmx/smv control structures. Since pt_freeze_time and pt_thaw_time use hvm_get/set_guest_time, they now no longer freeze TSC time for a guest. So, for timer_mode 0, TSC time is no longer frozen when a VCPU is not running. Unless you''re using opt_softtsc, in which TSC exactly tracks the per-domain values. I have no love for timer_mode...
