[Qemu-devel] Qemu's timer & Solaris9 issues.

[Karel Gardas]

Hi,

I guess all the problems with NIC driver and with keyboard auto-repeat are
(or might be) caused by a bit buggy Qemu internal timer. You can see it
the best at for example Solaris9 boot process, where boot manager
(Configuration Assistant) count 5 seconds to the boot, so 5, 4, 3, 2, 1,
boot -- sometimes this counting is done in less then 0.5 second (just
estimate) sometimes it's done in about 2-4 seconds, which is a lot better,
since then I have a good chance to have a bit slower keybord in
Solaris's xterm.... :-)

Does anybody here also do have similar problem with any other OS running
inside Qemu?

Thanks,

Karel

Just an addition to this report. Now, I've tried about 10 tries from which
I had one success where configuration assistant counting was really real 5
seconds counting. Interesting is that during this counting it prints ``No
RTC Timer?!'' and after it ``No RTC Date?!'' ?

These issues are perfectly duplicable if you download the first CD from
two CD sets of Solaris 9 installation (which also provides 3th CD of
additional languages supports and also once CD which is so called
``Installation CD'', but which is quite useless, since you can
install/boot directly CD1)

Thanks,

Karel

Yes.. When installing Win2k or XP the timer countdown to either boot CD or Hard disk runs past at 
different speeds each time I boot qemu..

Thanks for confirmation. Hmm, but then this issue might cause some quite
strange issues in the quest OS IMHO...

Fabrice, is there any good way how to debug it? Or even how to fix it
easily?

Thanks a lot,

Karel
