Network card name unstable across reboots

[msangi]

Hello, I just restarted by Proxmox VE machine to apply a new kernel command line option (cpufreq.default_governor=powersave, not sure if that matters).

Before the reboot my ethernet card was called enp3s0. After the reboot the host didn't come up in the network so I connected keyboard and screen to investigate and I discovered that during that boot the network card got assigned the enp4s0 name.
I then rebooted again and it got back the usual enp3s0 name.

Is there any way I can diagnose why the network name isn't stable across boots?

This happens if the interface is detected differently. The answer is in this link.

Thanks for your reply! Setting the name manually is going to solve the issue
