PVE displays wrong amount of RAM on dashboard

[dotmitsu]

Hello. I read many threads in forum about this issue. But I can't understand one thing.
I use Proxmox 8.1.11 with last updates.

As I anderstood in dashboard proxmox must show used memmory as used memory + buff/cache.


But I see this in dashboard


Ubuntu 22.04 server. qemu-guest-agent installed.
Is it normal? And why I see incorrect RAM usage in dashboard? Is ubuntu use some another memory which can be fast cleared and proxmox shows it as used?

Are you talking ONLY about a VM? Yes, PVE sees the memory different than your guest and PVE is always correct in showing what real memory is used.

For you output of free, this is also always the case that you have less than the real amount of memory available. Just check on any other platform and you will see the same.
