I guess you want to use this PCI-Card within the Windows Server 2003?
Well that won't work! The PCI devices can only used by paravirtualized 
guest not HVM guest.
As there is some development in this feature, maybe someday one could do 
it, but not now!
Check this for further information:

I have never really tested it but there is a way!
First of all you have to check wich ID your USB-device gets:

# lsusb

Then you have to add 2 lines to your hvm-config:

usb=1
usbdevice="host:xxxx:yyyy"

where xxxx:yyyy is the "ID" section in lsusb. I can not tell if this 
works with usb-flash-drives too, because I would think that there is 
some heavy load and maybe therefore it won't work.

You want to resize the domU harddisk? Hm, never tried it too, but if you 
use LVM in Dom0 and giving a lvm-partition to the domU, you could try to 
shutdown the domU, resize LVM partition and then, after starting domU 
again, try to use Partition Magic within domU to resize your filesystem. 
But, never did that too, and I don't know if it would break your 
filesystem?! So be carefull!

You can make a 1:1 copy of your image file, with cp or dd, I guess!?

> I can not find the image files for the doms.
Check your domU config-file, there you should find the path to your 
image file.
Hope it helps
