In our implementation, we don't start a new emulator. The codes can work,
but some bugs may be not triggered.
How do you reconcile the incoming QEMU save record with the running emulator
state?
We introduce a qmp command "xen-load-devices-state"(libxl__qmp_restore) which
can restore the emulator state. The step of resotre emulator state at a
checkpoint is:
1. libxl__qmp_stop -> vm_stop() in qemu
2. libxl__qmp_restore -> load_vmstate() in qemu
3. libxl__qmp_resume -> vm_start() in qemu

We will set to the guest to a new state, the old state should be
dropped.
