Getting my ethernet interfaces renamed on a stock install, please let me know if this is a bug, and how I can fix, thanks. I also cannot edit the "renamex:" interfaces from the proxmox gui.

It's not very predictable when everything goes to rename#!

I added the following to /etc/default/grub:

GRUB_CMDLINE_LINUX="net.ifnames=0"​

You need to do an update-grub2, then reboot.

Now you can create a file /etc/udev/rules.d/70-persistent-net.rules:

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="ethN"​

Replace the 'xx:xx:xx:xx:xx:xx' with the MAC address of your card, and 'ethN' with your network interface name. Reboot for your changes to take effect.

This is what I did (no other changes required)

root@pve:/etc/udev/rules.d# cat 10-network.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:25:90:4f:3c:68", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:25:90:4f:3c:69", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:25:90:4f:3c:6a", NAME="eth2"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:25:90:4f:3c:6b", NAME="eth3"

I tried the other options to get standard naming back, but nothing worked for me with the exception of above.

This worked for me as well, but after editing the file it was necessary to run the update-initramfs -u command so that they were recognized.
