[SOLVED] Network problem after upgrade 6 to 7

[hregis]

Hello,

Following the update from Proxmox 6 to 7, I followed a whole bunch of procedures and advice, but I can't get the network cards to work, I have error messages constantly scrolling (see all in down) and even by modifying the config of the interfaces to the bare minimum, like a first install, I don't have access from the outside. I specify that I installed "ifupdown2" as recommended by Proxmox 7 below is my setup. Do you have any info on this problem?
thank you

[spirit]

are you sure to have enoX interface ?

you're logs show "eth1", like you use old naming for interfaces .

also ,do you have tried with linux bridge instead ovs ?

Hi @spirit

I think I know where it came from, when updating from 6 to 7 I was asked if I wanted to replace the "/etc/default/grub" file with the new version or keep the current version, and like I had no info on the subject, I replaced the current version. It seems to me that in this file we can define the name of the interfaces (enoX or ethX)? How can I correct and put back "enoX"?

Thanks a lot

 

[hregis]

The solution is simple, remove these two parameters from "GRUB_CMDLINE_LINUX_DEFAULT" in "/etc/default/grub"

biosdevname=0
net.ifnames=0

thhen run an "update_grub2" and edit the "/etc/network/interfaces" file to replace "ethX" with "enoX"

I am closing this thread
thank you

Hi,I may have the same problem but not finding these two parameters. I followed also a whole bunch of procedures and advices and most are saying that eth0 is preserved if updated from a version 5. And that's my case.
On the other hand I am not finding ifupdown2 too as it is not been installed while upgraded.

Any advices please?
