QEMU: No filesystem info

[camrossi]

I am trying to gather, via QEMU the disk usage for my talos node but apparently this is not working.

This is a Talos cluster running inside OpenShift via KubeVirt
The virsh guestinfo 1 --filesystem returns nothing and also doing an API call to filesystemlist returns an empty list.

guestosinfo on the other hand works fine but also this one has no disks also the host name is not picked up.

{
 "fsFreezeStatus": "thawed",
 "fsInfo": {
  "disks": null
 },
 "guestAgentVersion": "9.1.0",
 "hostname": "(none)",
 "os": {
  "kernelRelease": "6.6.54-talos",
  "kernelVersion": "#1 SMP Mon Oct  7 18:53:44 UTC 2024",
  "machine": "x86_64"
 },

Wondering if I am missing something in my talos config?

If that feature is desired, you might need to figure out what is missing/develop that.

Talos API provides information about disks/filesystem usage.

Oh I think I misunderstood this extension then... I thought was the standard Qemu guest extension binary packaged in a way that can be installed but it seems this is created ad-hoc 😅

It is indeed a standard qemu guest agent binary, but like I said above, you should have better luck using Talos API.
