I am quite happy to report that it works with Windows 7 (32-bit).

What is interesting is that it works nicely with SeaBIOS (couldn't
the old BOCHS BIOS one to do PCI passthrough?). SeaBIOS does not
yet support PCI hotplug so I had to define the PCI entries in the
guest config, which means it was:

[root@phenom konrad]# cat /root/Win7.xm | grep -v \#
builder='hvm'
memory = 2048
name = "Windows7"
vcpus=2
vif = [ 'type=ioemu, mac=00:0F:4B:00:00:65,bridge=switch' ]
disk=[ 'phy:/dev/vg_private/Win7,hda,w']
vnc=1
videoram=8
vnclisten="0.0.0.0"
vncpasswd=''
stdvga=0
usb=1
usb_add="host:045e:0039"
usbdevice='tablet'
pci=['05:00.0','05:00.1']

(rev a1)


Linux on the other hand is more troublesome. This is with Fedora 20:

(nouveau kernel driver looks OK)

(so using nouveau)

And with Ubuntu 12.10 with Nvidia driver:  304.88-0ubuntu0.1
