 It's vioif(4).

 To use ixv,

	0) Add intel_iommu=on pci=assignbus to your kernel's boot argument

	1) Use "max_vfs=n" (e.g. n=8) when probing ixgbe
	   (e.g. add "options ixgbe max_vfs=8" into /etc/modprobe.d/ixgbe.conf)

	2) modprobe -r ixgbe; modprove ixgbe

	4) lspci. You will see some virtual functions. The number of
	   virtual function is the same as the number of max_vfs

	> 02:10.0 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)

	5) Add passthrough setting of a virtual function.
	   (You might want to add "blacklist ixgbevf" in /etc/modprobe.d/blacklist.conf)

	6) You might have to add some other variable settings
	   to your kernel's boot argument.
