            Bug ID: 296638
           Summary: Nuageinit network-config doesn’t work with “network”
                    key in yaml
           Product: Base System
           Version: 14.4-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: [email protected]
          Reporter: [email protected]

When using the following yaml with vm-bhyve’s “vm configure fbsd14-x64
network-config” using a FreeBSD 14.4 CI image
(FreeBSD-14.4-RELEASE-amd64-BASIC-CLOUDINIT-zfs.qcow2) nuageinit doesn’t set
the network (addresses changed to documentation ones)


network:
  ethernets:
    vtnet0:
      dhcp4: false
      dhcp6: false
      addresses:
        - 192.0.2.27/24
        - 2001:db8:cafe:1::1b/64
      gateway4: 192.0.2.1
      gateway6: fe80::2e3a:fdff:feed:3571
      nameservers:
        addresses: [2001:db8:cafe:1::53, 2001:db8:f00d:1::53]

After some tinkering in lua it seems the configuration is read in another
internal data structure with key “network” dus rendering it a bit like

network:
  network:
    ethernets:
        …

This seems to happen in the function parse_network_config()
(libexec/nuageinit/nuageinit) where a netobj["network"] = obj is done. That
probably needs to be a netobj["network"] = obj[“network”]. Of course it can
fall back to the old behaviour if the “network” key isn’t in obj.

The same config doesn’t as advertised (with different interface names of
course) with a Linux cloud-init bootstrapped VM
