According to the docs on http://qemu.org/qemu-doc.html#SEC45, Qemu "is able to boot a Linux kernel and to run a Linux Debian installation from NFS".

I downloaded debian-31r1a-mips-netinst.iso image, and tried to start it:

# qemu-system-mips -boot d -m 128 -cdrom debian-31r1a-mips-netinst.iso
mips_r4k_init: start
mips_r4k_init: load BIOS '/usr/share/qemu/mips_bios.bin' size 131072

The only thing that happen is Qemu window being open, black all the time.

When checked with "top", qemu-system-mips process takes about 70-80% of CPU time.

I created the /usr/share/qemu/mips_bios.bin file with dd command.

Why doesn't it start for me?

(A) You have to build a qemu-specific kernel to use the MIPS QEMU.

And how to build "qemu-specific MIPS kernel"?

Is it just a kernel built for MIPS, or perhaps some qemu-specific patches have to be applied?

(B) I have no idea if that method works with MIPS qemu; I only tested


I didn't quite understand what you mean.
