Dear reader,

Using qemu-kvm-0.13-rc1 and having the boot partition as if=virtio,
causes the attached blue screen when booting Windows XP SP3.
Changing the interface to ide (if=ide) and the system boots normal.

Do you have the virtio drivers installed?

Yes, everything is working fine when I use the 0.12.5 release.
Before you ask, I am using the git repository too. Same effect.

No suggestions form anyone?
Again, any compile combination is working under 0.12.5. Starting with
0.13-rc0/1 the virtio option for the boot disk is not working anymore.

Could you try bisecting please?
git bisect start v0.13.0-rc0 v0.12.0

will start the bisect process, then you build, test and run
git bisect good/git bisect bad as appropriate to get the
new version.

Following your advice, I noticed that the system could not boot when I use the guest virtio driver. I then switch back to as far as version 10.0 with the same bad result. I then remembered that in the past I used the '.raw' format. Since I am using the qcow2 format (better performance), I never tried if=virtio for the disk before until I use the 0.13.0-rc1 version. I tried the release tar file of 0.12.5 and this time with the guest virtio driver, with the same bad result.
Maybe it is the file format? Maybe the virtio disk driver? I have taken the virtio drivers from the KVM website.

Frans.
