I am currently using single NFS based PXE boot on eight nodes. I followed the guide on https://help.ubuntu.com/community/DisklessUbuntuHowto
Each nodes has a 1G and 10G network. Both of them are plugged in, i want to use 1G port for IPMI only and 10G for the regular networking.
But as the system boots, it activates both interfaces and assigns DHCP generated ip. How do i disable the first NIC on linux.
eno1 # 1G enp7s0 # 10G
I have my BIOS set to PXE from 10G only, and it is working as expected.
So far i have tried following in /network/interfaces (Different trials).
iface eno1 inet manual iface eth0 inet manual iface enp7s0 inet manual auto enp7s0 iface enp7s0 inet dhcp
I would rather have eno1 disabled or as backup interface instead of default on.
