Hi:

I have been trying to get Plan9 up and running on the latest Qemu
with the kqemu accelerator with no success. Before i start sending
kernel errors has anyone else worked on this ?

If you got errors, please post them, just make sure you have a recent
version of qemu and the latest Plan 9 iso.

Ok - here it is:

Started qemu like this:

marina@locutis:~/qemu-images$ qemu-img create plan9 7G
Formating 'plan9', fmt=raw, size=7340032 kB
marina@locutis:~/qemu-images$ qemu -hda plan9 -boot d -cdrom plan9.iso 
-net user

Typed 1 to install plan9

This is using ubantu linux with the current (not from cvs) qemu with kqemu
and the plan9 iso image downloaded on Jan 14. Compiled qemu with gcc 3.4
as it complained about using 4.0.

I got this error randomly on some machines. I tried with different
compiler versions,
different C libraries, different kernels, and found no pattern. The problem
is you dont get the code for kqemu...

The fix should then be obvious and easy.
Don't use kqemu.
ever.

That is what I concluded :-). I was just sharing my experience...

A question: have you been install some other guest OS on this set up?

I would try to reduce the size of file to less than 2GB and try again.

If that also fails try with smaller size file and no kqemu.
