How do I PXE-install Red Hat HPC compute nodes with Intel 10G NICs?

Solution Unverified - Updated -

Issue

We are trying to install Red Hat HPC compute nodes from the head node using PXE as described in the installation document:

http://docs.redhat.com/docs/en-US/Red_Hat_HPC_Solution/index.html

All nodes (including head node and compute nodes) use Intel 10G network cards. It seems that the NIC doesn't work without the OS installed, but we are trying to install from network.

We set the computer node to boot from network and booted it. We saw following error:

Media not detected...

Environment
