Qemu window size + windows XP resolution problem

Qemu window size + windows XP resolution problem

[Andrew Walrond]

Using v16 (including compiled modules) on a 2.6.20+ kernel, I installed 
windows XP as per the howto, which works perfectly.

I changed the windows screen resolution to 1280x1024x16 in the display 
manager, which resized the qemu window and works fine. However, after 
shutting down and restarting XP, the qemu window starts up at the original 
size and I can only see the top quarter of the windows screen.

Is this a known problem? Any way round it? I have found that resetting the 
windows resolution fixes the problem, but it's a pain having to do this every 
time.

Secondly, I have found that the mouse is sometimes not released to the X 
desktop after the session ends , resulting in a frozen mouse. I got round 
this by restarting a session, then ctrl-alt a couple to times to release the 
mouse before exiting the session again.


Niggles aside, I am very impressed. Great job!

Strange.  Does this reproduce with stock qemu-0.9.0?

I have a couple of XP VMs with non-default resolutions, and they don't 
exhibit this.

I've seen this with SDL-over-VNC.  What's your setup?  Distro, window 
manager, etc.?  Not that I know how to diagnose this, but maybe it will 
ring a bell for someone.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Don't know, but I'll try and report back.

I'm using Kubuntu Feisty (x86_64) on a Core 2 dell laptop , kvm built with SDL 
support.
