Amazon EC2 how to install ixgbevf on a Centos 7 instance?

I am trying to install ixgbevf on an instance of Amazon EC2 CentOS7. The steps look good, but every time I start the instance in extended network mode, for example M4.xlarge, the network seems to be unsuccessful (I can not connect to the instance after starting).

Here is what I did:

wget http://elrepo.org/linux/elrepo/el7/x86_64/RPMS/kmod-ixgbevf-2.16.1-1.el7.elrepo.x86_64.rpm
rpm -ivh kmod-ixgbevf-2.16.1-1.el7.elrepo.x86_64.rpm
cp -p /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak
dracut -f

Then turn off the instance and install sriov

ec2-modify-instance-attribute instance_id --sriov simple

It's all. Whenever a type (e.g. T2.micro) does not support Enhanced Networking, the instance works fine. But if I change the type to Enhanced Networking enabled (e.g. M4.xlarge), the instance simply cannot be accessed. Anyone got any about this? Did I miss something?
