Xenocode virtual appliance runtime11/13/2022 Also, they mainly focused present and future trends of virtual machine system, such as an overview of the future CPU architecture, the management mode of future memory and resource, the future maintaining method of system security and the performance evaluation method of future multiple virtual machine system.Rabi Prasad Padhy, et al (2011), surveyed the basic concept of virtualization, virtualization techniques, technologies, and services. YunfaLi,et al(2010), presented the technologies, such as virtualization, resource scheduling, migration, security and performance evaluation. However, for best fit and choice of hypervisor, adopter's virtualization requirements, organization size, personnel skills and computing workloads should be considered in advance. General findings of the study suggest high similarity in many aspects except that for adopters to attain maximum benefits of virtualized solutions based on open source computing will depend mostly on their adoption, usage and management practices which affect performance and security of virtual machines. This comparative analysis has focused on hypervisor strengths on virtual resource allocation, virtualization approach supported, server architectures, number of virtual machines, operating system compatibility for host and guest machines and management features. In this paper, Proxmox VE and XenServer as most popular type 1 open source based hypervisors are discussed and their functionalities compared. Use of open source virtualizations provides valuable IT solutions by enhancing high flexibility, scalability, security and performance. Performance measurement results show that Window 7 is the most suitable virtual operating system since it obtains the best performance when run on a Linux host.Īdvancement use of open source based type 1 hypervisors has transformed the way adopters manage their computing resources, lower IT operational costs and improved performance and flexibility. This paper presents a performance evaluation of three different virtual machines run by three recent versions of Windows operating system, namely Windows 7TM Professional, Windows 8.1TM Professional and Windows 10TM Professional, on a host computer system run by Linux Ubuntu. Emulated hardware is managed by virtualization tool that provides lower resources when compared to physical hardware. Each virtual machine is a separate instance that is completely independent and separated from the computer hardware and it runs on emulated hardware. It increases efficiency, flexibility and scalability of IT equipment by enabling different software-based environments on a single physical hardware. Virtualization has experienced a dramatic expansion recently and today is ubiquitous in modern IT industry since it provides numerous benefits to companies and individual users.
