1. normal installation. It stops for a while after that kernel
message you mentioned. For several secodns, mabye even 20
seconds. And after a while it continues. During all this
time the guest cpu usage is 100% like you describe (a tight
loop). This is what I call "working" - I never bothered to
think if that tight loop/pause is normal or not. This is
what happens for me with -cpu host.
OK, I see that, too.
2. with -cpu pentium it also displays that kernel message but
stops here without any cpu usage whatsoever. I waited for
some 40 minutes at one point (I just forgot I started it but
later on noticed there's a QEMU window floating around with
that NT kernel message on it and nothing happening).
Agreed. It stucks in a sti;hlt;ret, obviously waiting in vain for an
interrupt. Interestingly it works with -smp 2. Will further investigate.
3. In all other cases so far it BSoDs with STOP 0x3E error
right before displaying that kernel message.
MSDN talks about a mulitprocessor configuration error:

I suspected the offline CPUs in the mptable that confuse NT. But -smp
1,maxcpus=1 does not make a difference. I will try to dig deeper in this
area.
So.. I'm not sure if it's confirmation or not :)
I take this as one. Thanks for the clarification.
Regards,
Andre.
