Debian’s KVM + Ubuntu karmic => bug?

I’ve been playing with virtualization, and KVM in particular. However, I’m running into an interesting problem. Below is how Ubuntu Netbook Remix look inside my KVM (either using virt-viewer, virt-manager or directly KVM to display the VM). Note how the top panel is fine. I’m using KVM 88 from experimental (but I had the same problem with KVM 85 from unstable), the cirrus video driver inside the VM, and an up-to-date karmic VM.
Has someone ran into that problem already? If yes, where is it tracked? I’m been failing to find the correct search keywords so far.

  1. I’ve seen something that looked a bit similar when booting an Ubuntu install CD.
    However it was with qemu’s git HEAD and I think the problem never made it in a release.
    Just so you know, it was fixed by commit f22f5b077c164b864dae9776f63ed9e48a973fb6 in qemu.

    Do you still get the bug with standard qemu (no kvm)? Have you tried -vga std?

    Also I don’t really understand the versioning of the debian packages: kvm 88 seems older than qemu-kvm 0.11.0, although the maintainers say that the kvm package is a development snapshot while the qemu-kvm package is for stable releases. So maybe try the qemu-kvm package instead?

  2. I’ve tried qemu-kvm 0.11.0, same problem. 0.11.1 is not packaged in Debian.

    I haven’t tried qemu, because my image is using a virtio disk, I’ll try later today.

  3. Does Ubuntu Netbook Remix use a compositing windows manager? If yes, try to disable it. I experienced similar visual distortion when trying out mutter (resp. gnome-shell) on GNOME in a VirtualBox.

  4. The UNR launcher uses Clutter, which uses OpenGL. kvm would need to emulate a graphics card capable of 3d rendering.
