Very high memory usage. about proxmox_hassos_install

[whiskerz007]

Proxmox will report high usage due to the way QEMU reports VM resources without guest tools installed. If you run free at the root prompt you'll see actual usage of the VM.

[whiskerz007]

Please understand, this metric in the VM summary is Proxmox's reporting of usage, not the VM's OS actual usage. qemu will allocate the entire amount of memory given to the VM in Proxmox by design. The qemu agent reports back to Proxmox the VM's OS usage.

As of HassOS 3.6, qemu support has been added. With this support, the VM will report actual RAM usage, disk space utilization, and IP addresses of the VM. An update to the install script will set the QEMU Guest Agent flag for the VM. You can manually set this by going to the VM -> Options. (NOTE: Setting this manually without support can affect power related controls to the VM.)

You can check what version of HassOS you have by typing hassos info at the hassio > prompt. As long as version: reports greater than 3.6 you should not have any problems with setting the aforementioned flag.

That's great
Thanks for your work👍

I have noticed this problem

Hi
Are recently changes to hassOs (adding qemu agent ) will eventually fix this?

[whiskerz007]

New VMs created with script will now have the QEMU Guest Agent flag set. 46af8a3

Very Nice. Thank you.
How would I resolve "no guest agent running"

[whiskerz007]

You can manually set this by going to the VM -> Options.

hi i justa installed the latest proxmox and the hassio via the script and i am getting really high memory

[Dayve67]

I have had the same from day one when I installed.

If you're interested in seeing what the VMs actual usage is, you can type free -h at the # prompt in the VM to see free, cache, and used values of the memory. I do not have any control of how Proxmox displays the usage or how the VM reports it to Proxmox. If seeing the actual memory usage in Proxmox is of interest, then I would suggest you try HA in a LXC.

so this is the real memory usage ?as shown in the pic and not what proxmox says ,so i wouldnt mind what iproxmox says ?and one last question what do you think is the best config for memory and cores how many ?
thansk for your help

[whiskerz007]

Your Glances screen will show you the actual memory usage. I would go off of those numbers.

When I see the swap being used, that tells me it's time to increase the memory. Your screenshot shows that HA has 2.09GB of unused memory. Right now, you could afford to subtract at least 1GB of memory.

As for core count, there is little impact to HA by assigning more cores than necessary. If you have multiple VMs trying to use the same cores, Proxmox attempts to share the resource equally by default. If you would like to increase the priority of one VM over another, you can increase the CPU units of the higher priority, or decrease the lower priority. You can change that setting under the Processors hardware option.
