accuracy of the package comparison.
Less checkpoint more efficiency.

Xen COLO depend on qemu COLO replication function.
So, We need new qmp commands for Xen to use qemu replication.
Zhang Chen (3):
Migration: Don't load vmdesc when xen is enabled
Add a new qmp command to start/stop replication
Add a new qmp command to do checkpoint, get replication
Xen need't this.
