Thank you so much! You did a brilliant job! Works perfectly since this
morning. No idea what fixed it, maybe it was kernel 2.6.31-10 or
xserver-common.
Now the vesa-emulation (-vga std) works for me with karmic guest on
karmic host and I can get any resolution I want including my native one.
The
I'm marking the kvm and xorg tasked fix released, as I, too, can
confirm that we now have much better resolutions at our disposal in
Karmic.
I'm leaving the upstream QEMU task open, however, in that QEMU could
(should?) provide a better EDID interface.

Thanks for finding that patch, Marc.
Bryce is working on getting this into our cirrus driver for Karmic, so I
added a task for that package.
Also, I filed this bug against upstream QEMU. I can confirm that I'm
having trouble with -vga (anything other than cirrus). These video
modes should work
Yeah, this solution is a bit hackish but should be fine. A more proper
solution would be for kvm to more properly implement the virtual
monitor, by providing a dummy EDID structure... this is covered already
by bug 237164 and probably not something we're going to see soon, so for
now we can fix
This seems to be a general issue with the cirrus driver in the kernel. I found
the following post in the qemu forum, which provides an xorg.conf for a
1200x900 resolution:

Regrettably I did not manage to get any higher. Using '-vga std' is
One problem is that the emulated Cirrus card apparently only has 4MB of
video RAM, which effectively limits the 24/32-bit depth resolutions to
1152x864. You could probably go higher with 16-bit color instead.
I've been trying to use the alternate -vga std and -vga vmware
display devices, which

I'm marking this confirmed, as it seems that Kees is seeing something
like this too.
I have not reproduced the issue yet, though. I just installed the
Jaunty Desktop and it defaults to 1024x768.

I am using kvm -m 1024 -smp 2 image.qcow2 for launching the guest. I
tried various other options, but without higher resolutions.

fyi, fedora's got a patch in their cirrus driver that detects the kvm
pci id and sets the screen to 1024x768:

Currently I have a problem with my BIOS and it is not possible to
activate the virtualization support of the CPU. I used the default
xorg.conf with the changes described in the bug description.
