I have built a CentOS 8 base image from a kickstart, for use in OpenStack. This image boots fine but the problem I have is that I can't stop udev from renaming the network device from eth0 to ens<something>. I have /etc/sysconfig/network-scripts/ifcfg-eth0 with the correct HWADDR defined in it, and have set net.ifnames=0 and biosdevname=0 in the grub configuration, but nothing I have tried has stopped the renaming. I found this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1660179 which describes the same situation, but the comments in the bug didn't help. I'd like to keep the eth* device names because we have various heat templates and other scripts which assume that the network devices are called eth0, eth1 etc. Any ideas? Is this even possible with a CentOS 8 VM guest? Chris
