Re: [libvirt] [PATCHv2 libvirt] qemu: Issue rtc-reset-reinjection command after guest-set-time

rtc-reset-reinjection has been introduced because certain Windows

So if libvirt adjusts the guest system time via guest-set-time,
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)?
