[Qemu-devel] [PATCH 0/3] target-i386: save/restore vcpu's TSC rate during migration |

This patchset enables QEMU to save/restore vcpu's TSC rate during the
migration. When cooperating with KVM which supports TSC scaling, guest
programs can observe a consistent guest TSC rate even though they are
migrated among machines with different host TSC rates.
Haozhong Zhang (3):
target-i386: add a subsection of vcpu's TSC rate in vmstate_x86_cpu
target-i386: initialize vcpu's TSC rate to the value from KVM
kvm-all: notice KVM of vcpu's TSC rate after migration
kvm-all.c | 13 +++++++++++++
target-i386/kvm.c | 7 +++++++
