Description of problem:
Updating a Windows XP Pro VM to SP2 or SP3 (or installing directly from an SP2 or SP3 spin) causes the VM to fail.

Version-Release number of selected component (if applicable):
qemu-kvm-0.13.0-1.fc14.i686
kernel-PAE-2.6.35.6-48.fc14.i686

How reproducible:
Every time.

Steps to Reproduce:
1. Start with fresh install of Windows XP Pro and then update to SP2, or install directly from an SP2 or SP3 spin.
  
Actual results:
After the SP2 update of an otherwise functional instance of the OS completes and subsequently reboots, or immediately upon trying to instantiate the installation GUI of SP2 or SP3 spins, the VM's CPU goes to 100% and the VM console is totally black and unresponsive. The mouse icon disappears when moving it over/within the console window and it appears dead except for the CPU "spinning". 'Force Off' is the only way to shut down the VM and stop the CPU usage.

Expected results:
The SP2-updated VM should boot to the login GUI and the SP2/SP3-spin installation process should launch the installation GUI without the error.

Additional info:
Fully updated F14 host OS. The updates leading up to the SP2 update do not produce the error.  The SP2-updated VM starts/functions correctly and the desktop GUI is visible when started in Safe Mode.
