Memory Ballooning Not Happening. (Doc ID 2490802.1)

Last updated on JUNE 11, 2020

Applies to:

Oracle VM - Version 3.4.3 and later
Linux x86-64

Goal

Some virtualization platforms use some techniques to present to VMs more resources than the hypervisor have available. Examples are storage thin provisioning and memory ballooning.

The usage of Memory Ballooning consist of a virtual driver installed in the VM that reserve memory, causing the operating system in the VM see memory that is assigned to the system but not available to the applications. The memory that driver reserve from the operating system is not real memory, is in fact memory that does not exist. This driver will communicate with the hypervisor to allow dynamic memory allocation inside the VM.

Is there any option to configure Memory Ballooning support in Oracle VM?
