Kernel 6.8.12 doesn't allow network connectivity but kernel 6.2.16 does

[mygeeknc]

I just upgraded a PVE 8.0.x host to 8.2.3 and upon first boot after the upgrade, the host had no network connectivity. I rebooted the host and selected the 6.2 kernel and everything worked fine. Is this a known bug or how do I work around this?

Well, I've answered my question and putting this here for anyone who runs into again.

Under the new kernel, the NICs had new names. I had to go into the /etc/network/inferfaces file and change the adapters to match the new names that can be found under

ip a

and then reboot.

Thread 'No Networking After Upgrade to 8.2'

Apr 24, 2024

I upgraded to 8.2 and now have no networking connections. I still have the same IP, but cannot ping out from the machine to the network or any VM. I am also unable to ping the host. Obviously cannot connect to web interface or reach any VM. Any suggestions please?

I tried disabling pve-firewall and proxmox-firewall services and rebooting, did not help. I was not using the firewall previously.

I rebooted into the prior kernel and networking is working again. Any suggestions on debugging the kernel upgrade?
