BUG: unable to handle kernel NULL pointer dereference at 00000014

[Andrew Starr-Bochicchio]

On natty, I attempted to create a new virtual machine using virt-manager installing from an iso. As soon as the machine is started, the screen on the host becomes corrupted. Switching to a different tty and then back removes the screen corruption. virt-manager says the machine is running, but it is non responsive.

Hello, Andrew.
Can you tell the virtual machine parameters you've tried to create?

[Andrew Starr-Bochicchio (andrewsomething)]

I tried to create it with the virt-manager GUI so, I'm not entirely sure which parameters it is passing. Except for changing the size of the memory and the size of the storage, it pretty much followed all defaults. I reproduced it with `virt-manager --debug` Out put attached.

It's a known issue in kvm_amd, similar trace as bug 729085, I'm marking as duplicate.
