ethernet device naming em0 is eno16777738

Post by toocool » 2014/08/08 19:21:42

Im trying to setup a pxe boot environment to load up some centos7 boxes (vmware esxi guests) to test with but for some reason my ethernet device is being named eno16777738 which seems kind of dumb. Anyone know why it is not em0 like it should be?

pxelinux.cfg

Code: Select all

default linux
label linux
kernel boot/CentOS-7.0-x86_64-vmlinuz
append initrd=boot/CentOS-7.0-x86_64-initrd.img ramdisk=100000 inst.ks=http://foreman.example.com/unattended/provision ip=xxx.xxx.xxx.87::xxx.xxx.xxx.1.1:255.255.255.0:pxe-install:em0:none nameserver=xxx.xxx.xxx.6
I added default linux net.ifnames=0 but that changes everything back to eth0. I also tried biosdevname=0 but that had no effect.

Any idea what needs to be done so this device will come up as em0?
