Hypervisors Comparison and Their Performance Testing.

This paper is devoted to comparing approaches to the implementation of virtualization based on the use of the most common hypervisors. The paper considers advantages of using virtual machines while creating modern network infrastructure; as well as this, it describes a number of experiments on starting different hypervisors in one selected host along with the installation of two virtual machines with identical configurations. The results of CPU utilization and statistics on the use of a random access memory by hypervisors without virtual machines and with virtual machines are presented; conclusions on using different hypervisors are drawn.
