[Qemu-devel] KVM internal error. Suberror: 1 - emulation failure for FreeDOS 7.2

[agraham]

Hi Guys,

I was just doing some testing and decided to run Free-DOS under qemu-kvm 
1.1.1 under kernel 3.0.1 (I know it's old).

I downloaded the floppy disk image (1.44M) from the Qemu Testing page 
here: http://wiki.qemu.org/Testing

Then I ran:

qemu-kvm -fda odin1440.img

Just press enter on the default option,
then at the C:\> prompt type "help", e.g.

C:\>help <-enter->

This always results in:

KVM internal error. Suberror: 1

The above is reproducible 100% of the time (at least for me).

Given that this image is an actual example on the Qemu wiki, I would 
expect it to work.
