Memory Segmentation and Transfer in Mint Operating System

In order to utilize computer resources efficiently, technologies have been developed to enable running multiple OSes on a single computer. In our study, we developed the Mint operating system, which enables running multiple Linux instances on a multi-core processor. Mint is different from traditional virtualization technologies in that Mint can achieve performance isolation between Linux instances by segmenting computer resources. Currently, Mint statically segments and assigns its physical memory to each Linux instance. By transferring physical memory ranges among the Linux instances depending on their physical memory utilization, Mint can adapt to the load variations. In this paper, we describe the requirements for segmentation and transfer of physical memory and provide a solution.
