VF bus-info is null with xen4.4

[DKang4]

Hi guys!

I installed Ubuntu 12.04 LTS(Kernel version: 3.8.1) and Xen 4.4 to make VM using VF.

I use 2 82599 10G nic.

So I made some VFs and set "iommu=1" in GRUB like these.

And I also made VM(Paravirtualized Ubuntu 10.04 LTS) with 2 VFs. But...

it doesn't work...

Below, there are some information of Eth0(VF) by ethtool.

driver: ixgbevf

version: 2.11.3

firmware-version: N/A

bus-info: 0000:00:00.0

As you can see, bus address is null.

I also checked xen & ubuntu dmesg, but I can't find problem.

This is xen dmesg.
