Description

This test case verifies that the paravirt framebuffer works correctly for Fedora Xen DomU.

How to test

Make sure that the rawhide domU is configured to have a framebuffer. For instance, on a RHEL-5 dom0, make sure that the vfb parameter in the /etc/xen/rawhide config file looks like
```
vfb = [ "type=vnc,vncunused=1" ]
```
If you made changes to the config file, make sure to shutdown and start the rawhide guest again.
Inside the guest, enter runlevel 5 (if you haven't already done so), and check that there are no visual artifacts when using X, dragging around windows, etc.
Still inside the guest, open up an application that will use scrolling (Firefox is a good example), and try to scroll with your mouse.

No visual artifacts during normal usage.
The scroll wheel should work inside the guest.
No "invisible wall" is hit while moving the mouse from one side of the screen to the other.
