So suppose I have simple watchdog device that required to be poked every

The time is exposed (you can measure it by poking the device and measuring the time till reset) and will be described in the spec (otherwise users will be surprised when their machine resets).

You don't have to migrate all exposed state, just exposed state that the guest may rely on.
