As i understand it, reboot will do shutdown and initiate a run-command in order to send any updated parameters,
if this is correct, why vdsm and GA need to know its a reboot? guest is shutting down, no?

it would be better to add some info on stateless issue: when stateless vm goes down, its state is cleared,
so need to decide if reboot to stateless means also start with new state or no.

similar is vm from pool: when vm from automatic pool goes down, it "returns" to the pool, and not belong to a specific user anymore,
also here the state is cleared, so again need to understand the correct behaviour
