This patch probably isn't the right place in the stack to catch this,
but it seems to work for me.
With this patch, qemu doesn't crash for me.

Bug description:
12.04's qemu-kvm has been unstable for me and Marc Deslauriers and I
figured out it has something to do with the interaction of qemu-kvm,
unity and the vmvga driver. This is a regression over qemu-kvm in
11.10.
TEST CASE:
1. start a VM that uses unity (eg, 11.04, 11.10 or 12.04). My tests use
unity-2d on an amd64 host and amd64 guests
2. on 11.04 and 11.10, open empathy via the messaging indicator and click
'Chat'. On 12.04, open empathy via the messaging indicator and click 'Chat',
close the empathy wizard, move the empathy window over the unity luancher (so
it autohides), then do 'ctrl+alt+t' to open a terminal
When the launcher tries to auto(un)hide, qemu-kvm dies with this:
[10574.958149] do_general_protection: 132 callbacks suppressed
[10574.958154] kvm[13192] general protection ip:7fab9680ea0f sp:7ffff4440148
error:0 in qemu-system-x86_64[7fab966c4000+2c9000]
Relevant libvirt xml:
<video>
<model type='vmvga' vram='9216' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/>
</video>
If I change to using 'cirrus', then qemu-kvm no longer crashes. Eg:
<video>
<model type='cirrus' vram='9216' heads='1'/>
<alias name='video0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/>
</video>
The workaround is therefore to use the cirrus driver instead of vmvga,
however being able to kill qemu-kvm in this manner is not ideal. Also,
unfortunately unity-2d does not run with with cirrus driver under
11.04, so the security and SRU teams are unable to properly test
updates in GUI applications under unity when using the current 12.04
qemu-kvm.
I tried to report this via apport, but apport complained about a CRC
error, so I could not.
