Server construction using a server virtualization technique has increased due to its advantages including strengthening security, saving storage and costs, and efficient resource utilization. Particularly when the web server has a severe variation of number of users, server virtualization is used. However, constructing a multi-server with virtualization, compared to a single-server, there can be a drop in performance. In this paper, the authors construct several x86-64 servers based on open source server virtualization tools KVM and VirtualBox, and then analyze their performances using open source analyzing tools ab, httperf, and siege. The performance comparison arises in a single server and multi-server construction based on KVM and VirtualBox with a various number of virtual machines.
