rtc-reset-reinjection has been introduced because certain Windows

allowing rtc interrupt reinjection to compensate for lost time,
as well, will cause an incorrect guest system time.
So you should always use the
guest-set-time
rtc-reset-reinjection
pair.
But is that true both for the 'guest-set-time' no-arg case (which tells
the guest to read the current RTC and update in-memory time
accordingly), as well as the 'guest-set-time with time argument' case
(which tells the guest to forcefully set in-memory time, then write that
time back to the RTC)?
Yes.
Okay then. I'm posting v3 here [1] which unconditionally calls the
monitor command right after the guest agent command.
