[Xen-devel] Xen 3.4 multi-function pass-through tree, isn't working...

[Tom Rotenberg <tom.rotenberg@xxxxxxxxx>]

Hi,

I have cloned and compiled the latest Xen 3.4 multifunction
pass-through tree, you have published, and it doesn't seem to work.
I did the following:
1. Reboot the machine
2. Binded all the usb devices to pci-back, and made them all to be mmio aligned
3. Run the following command:
 xm create /etc/xen/hvm xen_platform_pci=0  pci='00:1a.0'
pci='00:1a.1' pci='00:1a.2' pci='00:1a.7' pci='00:1d.0' pci='00:1d.1'
pci='00:1d.2' pci='00:1d.7'

And i got the following error:
Error: int() argument must be a string or a number, not 'NoneType'

These are the last lines from xend.log:

Does anyone has any idea to what be causing this issue?
