Subject: [pve-devel] [PATCH container] fix #7156: setup: separate dns list with semicolons
Date: Wed, 17 Dec 2025 16:06:14 +0100 [thread overview]
Message-ID: <20251217150620.829190-1-m.sandoval@proxmox.com> (raw)
Network manager uses GLib's key file format [1]. As per `man 5
nm-settings-keyfile`:
> lists are separated by character ;
additionally, table 6 contains an example:
> Example: dns=1.2.3.4;8.8.8.8;8.8.4.4;

Running `nmcli` with this patch on a new rockylinux 10 container results in
```
DNS configuration:
servers: 10.10.10.2 10.10.10.22
domains: testinstall
interface: eth0
```
and
```
$ grep 'dns=' /etc/NetworkManager/system-connections/eth0.nmconnection
dns=10.10.10.2;10.10.10.22
```
and domain resolution seems to works as expected.
