Hi all,
I want to do ixgbe VF device passthrough by VirtualBox and just met one issue. 
After attached VF device and started guest, the assigned pci device can be found in guest. 
The detail steps and log listed below. Is there anybody can help me on that? Thanks a lot.

Boot host with iommu enabled.
Create VF device.
	echo 1 > /sys/bus/pci/devices/0000\:0a\:00.0/sriov_numvfs
Attached VF device to guest.
	VBoxManage modifyvm "fedora20" --pciattach 0a:10.0 at 01:05.0
Start guest.
	VBoxManage startvm "fedora20"	

Host log shown that VF device has been bound to pci-stub and iommu enabled.
