Log shows the inventory list has been correctly fetched but no valid IP returned.

API from PVE did returned with correct result when also using agent/network-get-interfaces:

{
  "hardware-address": "2e:6e:xx:xx:72:cd",
  "statistics": {
    "tx-errs": 0,
    "rx-dropped": 57183,
    "tx-bytes": 85102272373,
    "rx-packets": 200852685,
    "tx-dropped": 0,
    "rx-errs": 0,
    "tx-packets": 144342152,
    "rx-bytes": 199230248057
  },
  "name": "ens18",
  "ip-addresses": [
    {
      "prefix": 24,
      "ip-address-type": "ipv4",
      "ip-address": "192.168.10.9"
    },
    {
      "ip-address": "fe80::2c6e:xxxx:xxxx:72cd",
      "ip-address-type": "ipv6",
      "prefix": 64
    }
  ]
}

After attached debugger, hwAddr is not string equal to iface.HadrwareAddress resulting skip of a valid result because of string case sensitivity issue.

+1, was experiencing exactly the same issue. Cloning your branch from PR#12 instead instantly fixed the problem for me.

@andrew-d any chance of seeing this PR approved?
