Windows VM RAM usage

[dparadis]

Hi Guys!

ive got a wierd problem...
ive updated proxmox on the latest version since i needed support for my Windows Server2022
ive followed the guide to make it work and its been great for a while...
some day, ive installed Datto RMM and since my VM's RAM Usage got crazy (90%+ 24/7)
ive tried uninstalling datto but nothing...
tought i was a virus so i scanned the whole computer with multiples tools and event got a security analyst from Bitdefender look into it and there is no sign of malicious activity

i tried reinstalling Proxmox driver without success ...
since now my 2019 WinServer started to do the same...

anyone experiencing the same thing ?

Please post the output of pveversion -v of your machine.

Is the reported number of 90%+ memory usage within Proxmox or within your Windows machine? Do they both report the same amount of memory usage?

This seems to indicate that Windows isn't actually "using" all of that RAM, it might just be using most of your still available memory for caching, which is normal behavior on most operating systems. At least that's how I would interpret what's at fault here.

Did you install the QEMU guest agent and more importantly, the ballooning driver?

Also, what kind of Windows and which Proxmox version are you running?

I am seeing this as well with my only Windows based VM. From the minute I start the vm it will consume available memory until it crashes. It just started with the updates yesterday.

I think I spoke too fast, now it seems to be working correctly. No idea why it shut down on its own.
