Why KSM enabled but share bytes is zero?

What does your KSM configuration look like (cat /etc/ksmtuned)? IBy default, it does not start looking for pages to merge before 80% of host memory is used (free -m). If also works mostly (only?) on memory used for VMs and not containers. Maybe it did not find any lasting pages with the same content (cat /sys/kernel/mm/ksm/pages_sharing)?
The Proxmox Wiki has some links to more information about KSM: https://pve.proxmox.com/wiki/Dynamic_Memory_Management#KSM
