I've seen 3 variants here so far:

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.

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).

3.  In all other cases so far it BSoDs with STOP 0x3E error
  right before displaying that kernel message.

So.. I'm not sure if it's confirmation or not :)

Thanks!
