[Spice-devel] virtio and qxl windows xp driver problems with spice

[Mark Platek]

Hello all,

I'm using the latest unstable spice RPMs[1] on F13 and I'm having a few
problems that disappear when using qemu-kvm alone.

Firstly, virtio support appears not to work correctly when using spice.
I can start a spice server without the if=virtio flag on the -drive
argument and it will boot and everything is great. But, if I try to use
virtio, the server always crashes (I can watch xp bluescreen a few
seconds after booting from a spice client). I can use the virtio network
driver just fine. Here is an example invocation of qemu-spice that will
cause this behavior:

qemu-spice -spice port=5930,disable-ticketing -vga qxl -device AC97
-usbdevice tablet -enable-kvm -drive
file=/images/winxp.disk.qcow2,if=virtio -m 2048 -net nic,model=virtio
-net user

All information printed by spice before it crashes[*] is attached at the
bottom of this email. I can start the same VM image using qemu-kvm and
virtio will work just fine. In fact, I had to use qemu-kvm to install
the virtio driver in the first place. I am using the virtio driver that
can be found here[2], though others[3] exhibit the same behavior.

Also, qxl support appears to be broken somehow. Windows will recognize a
"VGA Controller" but will not install any version of the qxl driver,
including the old one found here[4] and the latest one I grabbed from
the spice website[5]. I can force Windows to install the driver, but
Windows then won't load it.

My plan is to compile the latest spice sources from git, maybe the
problem is fixed already. But maybe this information about virtio will
be helpful to you anyway.

If anyone has advice for using the virtio and qxl xp drivers with spice,
please reply.

Thanks,
Mark
