To provide education and particularly providing practical educational experiences to the students in the field of computing and information technology related courses including practical experience in the field of Networking, System Administration, and Operating Systems needs a lot of resources for the institution. Because this level of technical education can’t be provided only theoretically, students also need hands-on practical experience, and providing practicalexperience faces a lot of problems such as lack of funding and physical space, risks and threats to the network environment when we attempt to provide real, physical laboratory for experiments.This problem can be solved by developing a virtual environment for delivering students practical education. In this report we will look into different technologies used for virtualization today and do a comparative study. We will also explore some of the institutions, which are using virtual machines based environment to provide students practical experience in the field of computing and information Technology. And see how peoples are getting benefits fromusing virtual machines. We present how networks of virtual machines can be beneficiary for computing and information technology student and institutions by providing necessary environment in virtual network.
