I have nothing in my VirtualBox VMs directory other then my vdi file for
the Windows7 VM. A bit of searching led me to an Oracle article that
pointed me to ~/.VirtualBox/Machines/VM_NAME/Logs and there they were.

The failure is when the guest extensions load.

The problem goes away when I downgrade the drm kernel modules. I will now
try shutting down the VM and restarting wit the latest kernel modules.
