Hi,

I just noticed something weird. I have two Linux VMs with 1GB RAM each, both with ballooning enabled. Both use almost 100% of their RAM (at least according to proxmox) (~900MB).
If I deactivate ballooning on both, the RAM usage drops to about 500MB (also according to proxmox).
As far as I understand it, ballooning is intended to return unused RAM to the host and not to use as much RAM as possible.

Did I configure anything wrong? Both use the QEMU agent.
And is there any way to reduce buff/cache consumption?

Thanks in advance :)
