Power consumption of HAOS virtualized on Proxmox higher after Febuary update

Installation Home Assistant OS
1

Hello,
I am running HAOS on a Proxmox VE build on a N100 Mini-PC.
HAOS and the host normaly used about 5.5W - 6W. After a februray update of HAOS the system uses up to 3W more (9W). The only change was the update of HAOS.
Yesterday I tried a supervised installation on Debian 12 and this server runs at the former power consumption level of about 6W.
I think somthing changed in HAOS which leads to the additional 3Ws

Any idea?

Kind regards

@sairon any other reports of this?

I’d check for any change in CPU usage - if it’s caused by HAOS, there must be a visible bump in the Summary page of the VM in Proxmox.

If the Proxmox was updated recently, it could be also this effect of QEMU update discussed on Proxmox forums. It’d not manifest until the VM was restarted after the update.

Hi and thanks for the quick reply.
I don’t see any higher power consumption using another Linux.
Debian 12 and the supervised installation does not consume more power. It uses about 6W (host and HAOS together). Switching to the HAOS image and shutting down the Debian based one it goes up 3W.
I have set up the host and HAOS from scratch. No change in behavior.

CPU usage is not increased on the HAOS server.
So I do have no idea what causes this increase and I am not familiar with Alpine Linux to do more trouble shooting.

Edit: I will check the pve-qemu-kvm version. Thanks for the link.

Kind regards

Hi,
sairon your link contained the solution.
Version pve-qemu-kvm=9.2.0-3 solved it.
Now it runs at 5.5W - 6.2W again.

Thanks a lot!
Kind regards
