Everything working after power outage except one VM which lost internet connection. Different from the other similar issue.

[bepstein111]

Hi all, very confused here:
Today my power went out due to the heat, and when it came back on, everything on my proxmox instance looks fine, except for one single VM (which is identical to three others which are all fine) which can no longer connect to the network/internet. No devices changed names. Here's what I've tried:



Happy to provide anything else that would be helpful.

Thanks in advance!

Thanks, it looks the config correct, so the issue seems on the VM.
The network config on the VM doesn't sees to include auto start (auto) [0]; could you try to bring the interfacr up on the VM:
~# ifup enp6s18

Which Linux distribution running on the affected VM?

Please attempt on the VM as below:

~# ip link set enp6s18 down
~# ip link set enp6s18 up
