No, it isn't.  To introduce -rtc properly, you should use QemuOpts.  We

Yes, QemuOpts is a must-have for -rtc. So you agree to introduce -rtc
(in addition to the qdev-based configuration, of course)?

Yup.

Hard to say.  Doesn't the rtc keep track of wallclock time even on power
off?  I think using host_clock unconditionally does actually make sense.


Moreover, quite a few (of not all?) other RTCs use the host time
already. Well, I would be happy to avoid that 'clock' knob. So if there
are no concerns, I will unconditionally switch MC146818 to host_clock.
