[Stefano Rivera]

Binary package hint: kvm

System: MacBook running gutsy/amd64:
ii kvm 1:28-4ubuntu1 Full virtualization on x86 hardware
ii linux-image-2.6.22-9-generic 2.6.22-9.25 Linux kernel image for version 2.6.22 on x86/x86_64

I'm running XP SP2 as a guest:
Works fine:
$ kvm -hda qemu/xp.img

Spews errors and crahes when XP tries to switch the display mode:
$ kvm -hda qemu/xp.img -std-vga
kvm: get_dirty_pages returned -2

This is apparently fixed in kvm-36. I might look at merging debian's new kvm.

I'm experiencing this too on my Thinkpad T61p. Very annoying, since -std-vga is needed to run full-screen on wide displays. It has indeed been fixed upstream.

[Matt Darcy (matt-darcy)]

Is there any movement on this at all, we've had 5 months pass with no sign of a kvm update

[Nick Barcet (nijaba)]

Thanks a lot for your bug report. As KVM is moving to main with Hardy, we have been working very hard on it. If you are able to upgrade to the current development version, it would certainly help to know if your problem is fixed with this new version, as I would tend to think it is.

I have experienced exactly the same bug with KVM version installed from Ubuntu repositories.

Amd 64
Windows xp SP2 guest
-std-vga option

I have downloaded kvm-61 sources from sourceforge (http://sourceforge.net/project/showfiles.php?group_id=180599)

# ./configure –prefix=/usr
# make
# sudo make install

(needs gcc3.4 and libsdl-gfx1.2-dev)

then sudo modprobe kvm_amd

Lauched kvm
# qemu-system-x86_64 -no-acpi -m 512 -std-vga

No more bug.

With the hardy version of kvm this now works correctly. This bug however has [gutsy] tag so im not sure if it should be closed as fix released or not.
