Xen Windows DomU

My Xen DomU Windows Configuration File passes two USB 2.0 Controllers and my ATI Graphics card for Secondary VGA Passthrough:

cdelorme@xen:~/hvm$ cat windows
name='windows'
builder='hvm'
vcpus=4
memory=6144
disk=[
	'/dev/xen/windows,,hda,w',
	'/dev/nas/software,,sda,w',
	'/dev/nas/media,,sdb,w',
	'/dev/nas/special,,sdc,w',
	'/dev/nas/dumpbox,,sdd,w',
	'/dev/nas/family,,sde,w'
]
vif=['bridge=xenbr0,model=e1000,mac=5a:50:a3:14:b1:1c']
pci=['01:00.0','01:00.1','00:1a.0','00:1d.0']
boot='c'
pae=1
nx=1
nestedhvm=1
viridian=1
videoram=16
stdvga=1
vnc=1
vnclisten='0.0.0.0:10'
vncpasswd=''
usb=1
usbdevice='tablet'



I am using Debian Wheezy for my DomU, and I use a DomU PFSense for my network, with Dom0 and my other machines inside the network.  My interfaces file has two bridges:

cdelorme@xen:~/hvm$ cat /etc/network/interfaces
auto lo xenbr0 xenbr1
iface lo inet loopback
iface eth0 inet manual
iface eth1 inet manual
iface xenbr0 inet static
	bridge_ports eth1
	address 10.0.0.2
	netmask 255.255.255.224
	gateway 10.0.0.1
	dns-nameservers 10.0.0.1
iface xenbr1 inet manual
	bridge_ports eth0



I compiled a custom Linux Kernel to embed Xen-PCIBack among various other modules.  This way I can pass devices from the Grub configuration, it was easier than it sounds.  Here is my GRUB entry (/boot/grub/grub.cfg) for Xen:

menuentry 'Debian GNU/Linux, with Xen 4.2-unstable and Linux 3.3.3' --class debian --class gnu-linux --class gnu --class os --class xen {
        insmod part_gpt
        insmod ext2
        set root='(hd0,gpt2)'
        search --no-floppy --fs-uuid --set=root 1229b41c-108e-4e26-a78b-3a958e9acc2b
        echo    'Loading Xen 4.2-unstable ...'
        multiboot       /xen-4.2-unstable.gz placeholder
        echo    'Loading Linux 3.3.3 ...'
        module  /vmlinuz-3.3.3 placeholder root=/dev/mapper/xen-linux ro  quiet xen-pciback.hide=(01:00.0)(01:00.1)(00:1a.0)(00:1d.0)
        echo    'Loading initial ramdisk ...'
        module  /initrd.img-3.3.3
}
menuentry 'Debian GNU/Linux, with Xen 4.2-unstable and Linux 3.3.3 (recovery mode)' --class debian --class gnu-linux --class gnu --class os --class xen {
        insmod part_gpt
        insmod ext2
        set root='(hd0,gpt2)'
        search --no-floppy --fs-uuid --set=root 1229b41c-108e-4e26-a78b-3a958e9acc2b

        module  /vmlinuz-3.3.3 placeholder root=/dev/mapper/xen-linux ro single
        echo    'Loading initial ramdisk ...'
        module  /initrd.img-3.3.3
}
