Issue on ram usage

[maxencefiu]

Hello !
I have a problem on one of my VMs. A windows server VM consumes 100% ram (64gb) and CPU (24 cores) in its task manager but when I list the processes it really only uses 10gb.

The windows server side :

Proxmox side :



What could be the cause?

Windows Taskmanager has a "Details-Tab" where you can show more fields about memory.
The Process-List does not really show all memory a Process has allocated....

What do these "Command Processors" do? Running an application or something?
Consider an AV-Scan....

Even in the detailed version it uses no more than 8 gb, there are no viruses. It seems to be a misconfiguration I did on proxmox or I don't know.

Did you set Task-Manager like this?

Balooning enabled in PVE?
virtio-drivers installed?

I reinstalled virtio manually with the exe. It cleared the ram but not the CPU.
Yes balooning enabled.

Disable balooning, set processor to HOST....

PVE-Version?

ram usage on proxmox dashboard is VM ram usage + linux disk cache + arc cache (if zfs being used)

so this gauge is not perfect for getting an overview on real ressource usage

Ok I managed to patch apparently following your help, however the VM ram goes up without me doing anything on it. It goes up until it reaches its maximum. The version is : 7.4-13

I guess he is talking about 97% Usage shown in Taskmgr in his Srv22 Guest....
Dashboard looks normal to me... but why is the Guest at 97%? What workload is running inside VM?

I've talked to people who know more about it than I do, and they tell me it's a bug that's not currently patching balooning on Windows. This sometimes happens on randoms VMs, or even all of them, and there's nothing we can do about it.

so, if more then one person tell this is a balloning bug - what's the bug id / link for this ?

Can you please show VM Config in Proxmox? Do you have an lower limit set in Ballooning?
