Hi All,
I have just installed Slackware64 13.0 64-bit Linux as 
HVM domU. Please refer to 
http://enmingteo.wordpress.com/2009/11/01/picture-tutorial-how-to-setup-slackware64-13-0-hvm-domu-with-xen-3-5-unstable-pv-ops-dom0-kernel-2-6-31-4-in-fedora-11-x86-64-dom0/ 
for more details and screenshots.
I have tried to passthrough the 
firewire controller on Intel DQ45CB motherboard to Slackware64 13.0 HVM domU but 
I can't load the kernel modules for it.
Please have a look at the 
following output within Slackware64 13.0 HVM domU.

From 
  the screenshots of the device manager in the Win XP Home domU,
the OHCI 
  IEEE 1394 firewire controller appears to be working properly.
The Windows 
  drivers for the firewire controller reports that the
firewire controller is 
  working fine.
However, when you connect a firewire-based digital video 
  camera to the
firewire port, it is not detected in the Windows virtual 
  machine.
I will probably have to find time to install a Linux HVM domU 
  and try
to pass through the 1394 controller to it.
