VM info for ethernet device and IP and other VM information not automatically created and associated

[quiknick]

Currently only LXC container IPs and interfaces are recorded, but not VM IPs, MACs, interfaces and hostnames, even with QEMU agent installed.

Option 1: use qemu-guest-agent to get info

apt install qemu-guest-agent
enabling the Guest agent flag in the VM config (in the GUI -> VM -> 'Options')

Proxmox VM Summary now lists IP and actual interface.

Use pvesh commands in following comment to get interface name, IP address and hostname.

Option 2: Use arp to get basic IP info

Look for the mac address in the configuration of the vm. In my example: vmid = 1176

Code:
~# qm config 1176 | grep net
boot: order=scsi0;ide2;net0
net0: virtio=4E:57:9F:01:4E:6F,bridge=vmbr12,firewall=1

Now you can use "arp" to get the current IP address from the MAC:

Code:
~# arp -n | grep -i 4E:57:9F:01:4E:6F
10.12.4.59 ether 4e:57:9f:01:4e:6f C vmbr12

and get hostname

pvesh get nodes/pve4/qemu/105/agent/get-host-name
┌────────┬────────────────────────────┐
│ key │ value │
╞════════╪════════════════════════════╡
│ result │ {"host-name":"playground"}

of course with any of these commands you have to know what host the vm is on, then use the vmid in concert to get info.

If I understood it correctly, you wish to have IP address information of Virtual Machines and Containers also synced on Netbox? If so, I agree with it and I am going to work on it later on!

As you said, Virtual Machines needs to have Qemu Agent installed on it so that I can get this information and make it available on Netbox. While LXC containers is already ready for API integration through REST API.

Hi @emersonfelipesp ,

It works as intended on our setup (5 nodes, 100+ vms).

I'll open a PR.

cheers.

[maxdallmair]

Any Update on this, when it goes live?

Thanks Max!

[MrBE4R]

Hi,

This has been merged with release v0.0.5, just be aware of #88 and #94.

Cheers.

[maxdallmair]

Okay, but there are still no IPs in Netbox, or? All my KVMs have gust agents and i see the IPs in Proxmox

[MrBE4R]

Can you open a new issue and share the logs ?

[emersonfelipesp]

I'm closing this discussion, since @MrBE4R and @maxdallmair helped deploying Network integration with Proxmox and NetBox!
