ixgbevf: Unable to start - perhaps the PF Driver isn't up yet

[didi8206050]

I try to enable ixgbevf, the procedure is here:

1. enabled SR-IOV support in BIOS
2. enable IOMMU support: intel_iommu=on
3. create /etc/modprobe.d/ixgbe.conf, and the content is: 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 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)
03:14.0 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)
03:14.1 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)
03:14.2 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)
03:14.3 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 vNIC from SR-IOV cannot be brought up, after "dmesg | grep ixgbe", it says:

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