networkd didn't work

[rcambrj]

For some reason the recommended configuration in the README didn't work for my OVZ VPS on ethernetservers.com.

The venet0 interface should look like this:

But after rebooting it would never gain an IP address. It would just always look like this:

Instead, and for those at a loss, I switched to whatever nixos uses when networking.useNetworkd = false:

  networking.useNetworkd = false;
  networking.useDHCP = false;
  networking.interfaces."venet0" = {
    ipv4 = {
      addresses = [
        {
          address = "89.117.152.xxx";
          prefixLength = 32;
        }
      ];
      routes = [
        {
          address = "0.0.0.0";
          prefixLength = 0;
        }
      ];
    };
  };
  networking.nameservers = ["1.1.1.1"];

I don't get the venet0:0 alias, but it works:

Thanks for your hard work @zhaofengli 🙂

Interesting, I don't have a server with EthernetServers anymore, but networkd works fine on my other OpenVZ nodes with nixos-unstable. Could you try the following and see if networkd emits any interesting logs?

  systemd.services.systemd-networkd = {
    environment = {
      SYSTEMD_LOG_LEVEL = "debug";
    };
  };

there are a bunch of failures in this log, but I don't know whether any of them are relevant 🤷

This might indeed be because I've misconfigured something, but from what I read, OpenVZ 7 runs on kernel 3.10 with Virtuozzo's patches to make it look like a more up to date one. That's pretty vague and obscure to me, so I'm going to abandon OpenVZ in favour of a KVM VPS. Not trying to steer anyone in any direction with this, only justifying that I won't investigate this any further.

Thanks again :) I hope what I put here helps someone at least.
