Like the title says. I installed a GPU, everything posts and boots fine. The lights on the Ethernet port are lit up and will stay lit up indefinitely (I assume) if I leave it at the kernel select screen.
But as soon as I load a kernel, the lights go dark. It also is not shown as an active client on my gateway, so it’s not working at all.
I’ve tried lots of commands I’ve found to force it up. It looks to me like the NIC assigned to vmbr0 is correct. Etc. I just can’t get it to work.
If I remove the GPU, it immediately works again. NIC stays up after the kernel loads and I can access the web UI as normal.

I am not at home, but what I did was change the 99-default.link file. I found this from the two pages below. https://wiki.debian.org/NetworkInterfaceNames#CUSTOM_SCHEMES_USING_.LINK_FILES https://wiki.debian.org/NetworkInterfaceNames
Basically, by doing this, your nic cards will be forcibly named using the mac address:
#/etc/systemd/network/99-default.link [Match] OriginalName=* [Link] NamePolicy=mac MACAddressPolicy=persistentAfterwards, you will need to reboot and then update your network config file to use the correct names. I don’t ever change the network config with the GUI in proxmox as it has wrecked it too many times. I will update this reply again later with some more information on what to do.
