Nowadays cloud-computing systems take a great advantage of virtualization for the benefits of workload iso- lation and flexible resources partitioning. It is expected that the same functionalities will be available also on disaggregated architectures, proposed recently as next generation approach for building data-centers. In this publication, we are presenting the design and prototype of an enhanced virtualization layer, enabling runtime memory balancing between virtual machines on a section granularity. Guests’ RAM is backed by isolated chunks of host memory, coming from independent physical banks, not necessarily a local one. It can be dynamically resized without requiring any support for the ACPI emulation in the virtualization framework, as we exemplified by implementing the prototype on ARMv8 platform.
