I have improved on manual focusing using my digital video camera.

This video shows Xen 3.5-unstable (changeset 20143), VT-d, pv-ops dom0
kernel, VGA passthrough, HD audio passthrough, and Windows XP
HVM guest operating system in action.

Host Operating System Domain 0: Fedora 11 Linux x86-64 64-bit
Domain U: Windows XP Home Edition SP3 32-bit HVM Virtual Machine
Xen Hypervisor Version: 3.5-unstable changeset 20143
Paravirt-Operations Dom0 Kernel: (Jeremy Fitzhardinge's git tree)
Intel GFX Passthrough Patches Applied: Version 1 (Provided by Han Weidong Intel)

Motherboard: Intel DQ45CB
BIOS Version: 0093
Processor: Intel Pentium Dual Core E6300
Graphics Card: nVidia GeForce 8400 GS PCI Express x16
Memory: 8GB DDR2-800

Version of Xen GPL PV (GPLPV) Drivers Installed: 07/15/2009

Full implementation details are here:

VGA and HD audio passthrough are fully working. Although device
manager reports that it is working, OHCI IEEE1394 firewire controller
passthrough is not working as expected. Video cameras with firewire
attached to the firewire port cannot be detected.
