After finding the cause of the other problem (in the thread
"Booting/Installing Windows NT", all thanks going to Andre
Przywara), I can proceed with this issue finally.

I tried installing winNT here on old kvm and upgrading kvm.
So far I can say that if winNT were installed with kvm-72
and later, it boots just fine in kvm-0.12.

So I don't know what the problem is in this case.  Maybe
it is becauese the OP installed his winNT guest before
kvm-72 and now in 0.12 the guest is not able to find its
filesystem anymore, or maybe it's because there was some
bug fixed in service pack 1 (which I used here) that makes
the problem go away - I dunno.

But having in mind how picky winNT was for the hardware
changes, I don't think it's worth the effort to debug
this problem further - winNT is really ancient system,
and having upgrade path for kvm from some ancient
development snapshot to current version isn't that
important, IMHO.  Yes, a few people will be hit by this
issue, which is a sad thing, but seriously, we've more
interesting things to do ;)

Thanks!
