RAM usage mismatch between Proxmox and ZimaOS

[sabinmj]

What happened?

Description

Running ZimaOS+ v1.5.4 on Proxmox 8.1.4.

RAM usage shown in Proxmox UI and ZimaOS is very different.
Not sure which one is correct.

Environment

• ZimaOS: v1.5.4
• Proxmox: 8.1.4

Expected

Both should show similar RAM usage.

Not a ZimaOS dev, but this looks similar to how Linux/KVM reports memory.

What you're seeing might be "allocated" vs "actually used" memory.
For example, the host (or hypervisor) can reserve memory for VMs or cache,
which shows up as used, even if it's not actively consumed.

Depending on where ZimaOS reads its metrics from (e.g. /proc/meminfo vs a higher-level API),
you can end up with different numbers than tools like free -m.

So this could be more about how memory is reported rather than a real leak or mismatch.
