That’s what the automatic ballooning series is about. As soon as the service is started, also the memory information displayed on the Proxmox VE GUI is identical to the value shown in the windows task manager see screenshot.


Dynamic Memory Management

Someone or some tool is supposed to be watching the pressure in the host and guest and then operate the balloon accordingly. The balloon has to be automatic in order to be really useful.

I previously wrote about it here. First, the size of the balloon is controlled by the host, not the client; as far as I can see there is no way to increase the balloon from the clients side. Consequently I am an atheist [To nutcases: For example, a 2G host running two VMs each with 2G would be over-committed.

The VM decides which processes or cache pages to swap out to free up memory for the balloon. You can adjust this manually for your guests, either by editing the XML, or by using the virsh setmem command.

The balloon itself is non-swappable and un-killable in case you were wondering. To inflatewhich means, to return memory from the guest, run the below command, lihux returns 10MB of memory back to the guest.
