Fresh install of Proxmox over Debian 11 Erases Network Configuration

[wavesound]

Hi,

I had installed Proxmox 7 on Debian 11 using the guide here: https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_11_Bullseye

However, after rebooting the system after completing the installation, I discovered the Proxmox disabled the autostart on my ethernet interface. I think this is a bug?

Thanks for the report, can you workaround that by setting the autostart checkbox for the interface over the WebGUI's Node -> Network setting, after using ifup once manually to bring network up.
Or more ideally you add already a Linux bridge (the default name would be vmbr0) and configure the actual NIC as bridge-slave.

Manually editing /etc/network/interfaces can be done too, naturally:

I think this is a bug?

Yes, we noticed that on some tests here last week, and it's being worked on.

Enabling autostart in the WebGUI seems to have resolved the issue. Thank you for following up @t.lamprecht .
