1. Enabled the SR - IOV support in the BIOS
2. Enable IOMMU support: intel_iommu=on
3. Create the/etc/modprobe. D/ixgbe. Conf, and the content is: the options ixgbe max_vfs=32
4. Rebuild the initramfs image to include the file/etc/modprobe. D/ixgbe. Conf: sudo lsinitrd/boot/initramfs - 3.10.0-327.13.1. El7. X86_64. Img/etc/modprobe. D/ixgbe. Conf
And when I lspci | grep Virtual, it displays the like this:
03:13. 1 Ethernet controller: Intel Corporation 82599 Ethernet controller Virtual Function (rev 01)
03:13. 2 Ethernet controller: Intel Corporation 82599 Ethernet controller Virtual Function (rev 01)

03:13. 7 Ethernet controller: Intel Corporation 82599 Ethernet controller Virtual Function (rev 01)

03:14. 4 Ethernet controller: Intel Corporation 82599 Ethernet controller Virtual Function (rev 01)
03:14. 5 Ethernet controller: Intel Corporation 82599 Ethernet controller Virtual Function (rev 01)
But the new vnics from SR - IOV always be brought up, after "dmesg | grep ixgbe", it says:

My NIC is Intel 82599, the driver is ixgbe and ixgbevf, My operation is centos: 7. I 'v no idea, does anybody know the problem?
