[PATCH v2 0/3] target-i386: save/restore vcpu's TSC rate during migration

2015-10-20 Thread Haozhong Zhang
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. A pair of cpu options
