iPXE support for recent EC2 M5 instances - zendes - 2018-03-14 01:51

Hi All,

I'm trying to determine if I'm doing something wrong or if the network adapter in the latest EC2 M5 generation simply isn't supported.

I've build iPXE using the commands in http://git.ipxe.org/ipxe.git/commitdiff/cc25260, but I'm using the latest commit (d8c500b7945).

I then import ipxe.usb into EC2 and turn it into an AMI.

When I launch something like a t2.micro with it, it detects the network interface (net0) and can configure it.

When I launch any M5 instance type (or really anything that uses ENA from https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.html) net0 doesn't show up.

The best example I have is that an m4.10xl will have net0, and m4.16xl will not. Has anyone had any success with the ena driver, and do I maybe need to turn it on/register it when compiling iPXE?
