I do not know. What I was trying to say is that it is weird if Minix (note that 
I was not meaning
Linux) works fine:
- - on bare hardware
- - on QEMU (without kqemu)
but does not work on QEMU with kqemu. Minix developers say that it is bug 
somewhere in kqemu.

Bug in Minix is not relevant (to others) but if it revealed some bug in kqemu, 
this may be
interesting to other operating systems too.

[Qemu-devel] bug (?) related to kqemu and/or Minix3

Hello,

I (and others) have observed the following problem with kqemu

If you take Minix3 harddisk image such as:

http://altair.sk/uploads/minix.img.gz

and if you try to boot it via QEMU without kqemu

qemu -hda minix.img -no-kqemu

there are no problems.

However, if you do the same but you try to use kqemu

qemu -hda minix.img

booting of the kernel halts in the middle.

Do you think that this is a bug in Minix or in kqemu module?

Best regards
