Hello, I found some issue . One of my VM running on Ubuntu 22.04 LTS which has a file processing app. For test purpose qbittorrent installed to perform IO and UL/DL simultaneously
Inside the VM nothing suspicious
Memory consumption look normal inside Just 1.3 Gig

When I switch over to Proxmox host the VM eating up almost all assigned memory after a while (5-10 minutes)

-qemu agent installed
-Disks does not utilize any cache

Balloning on/off does not helped, disk cache settings does not have any effect.

Test:
When I gonna download any files using torrent, memory consumption increasing dramatically on the host, not on VM.
So strange....


Any suggestion welcome
