[Qemu-devel] [PATCH v6 3/3] target-i386: add support to migrate vcpu's TSC rate

2015-11-23 Thread Haozhong Zhang
This patch enables migrating vcpu's TSC rate. If KVM on the destination machine supports TSC scaling, guest programs will observe a consistent TSC rate across the migration. If TSC scaling is not supported on the destination machine, the migration will not be aborted and QEMU on the destination wi
