Hi,
I have a proxmox server with a quad NIC card + 2 onboard NICs. I initially installed Proxmox 6 on it a few months ago and ran into issues related to the interface names, which were being named RENAME1, RENAME2 etc.
I found several threads related to this and resolved the issue by creating /etc/systemd/network/99-default.link with the following contents:
My /etc/network/interfaces file contained
As you can see, nothing fancy and I'm currently not using any NIC apart from the primary onboard one.
I have just done an upgrade from V6 to V7 (7.1-5) on this machine. The actual upgrade went fine but after reboot I had lost network connectivity.
I discovered that the primary interface had changed back to eth0 ???
ip link shows:
So, I have currently resolved the issue by modifying /etc/network/interfaces to add
and modifying the vmbr0 definition to use eth0 instead of eno1.
Does anyone know why this has happened and whether there is a better way to fix the naming ? I assume that I should probably be using the new interface names, but I'm currently unclear why it has reverted to old style ?
Thanks
