Recently I exported several VMs from vmware and imported them into proxmox. I could not for the life of me get it to recognize my ethernet interface. In the VM I was not seeing eth0 or any interfaces related to ethernet. I tried all sorts of things such as updating my interfaces file, using netplan instead of ifconfig, etc. None of these solved my problem. I was getting really frustrated when I read this post: https://forum.proxmox.com/threads/networking-issue-on-some-vms-but-not-others.85819/
I then decided to run the command:
against a working VM and the newly imported one. A diff of these showed:
I quickly noticed the net0 section missing from the newly imported VMs config so I added the line:
(note that I modified the MAC address to not match the mac of the other VM). Essentially I am telling proxmox what driver to use with this VM and the name of the interface on the proxmox host itself. I then rebooted the VM and it got an eth0 interface and an IP address!
Hope this helps someone!
