Hypervisor - Term Paper Example The server virtualization also allows the organizations to run different software applications on diverse operating system to fully utilize system resources of a single physical machine. The operating system can run in isolation and / or side by side on the same physical machine. Each virtual machine (operating system) has its own allocated virtual hardware (e.g. Random Access Memory, Central Processing Unit, NIC, etc.) to load one operating system along with software applications. It is vital to state that the operating system uses the allocated virtual hardware resources, consistently and usually regardless of the actual physical hardware components (Bento, 2012). Advantages of Hypervisor Several advantages can be availed by an organization utilizing the technology of server virtualization. The server virtualization facilitates the organizations to combine the workloads of the underutilized server machines onto a smaller number of fully utilized machines. Keeping in view the fact o f utilizing comparatively less number of servers for the multiple operating systems and software applications to manage the workload, it can be stated that the server virtualization can be cost effective for the organizations. ...

The disadvantages of utilizing hypervisor in the enterprises include but are not limited to the requirements of servers with high specifications (i-e Randon Acess Memory, Central Processing Unit etc.), it requires additiona l hardware components and difficult to use console interface. The type two (2) or host hypervisors lead to the loss of centralized management, it has lower density and therefore, it becomes difficult to install many virtual machines of the first type. The organizations have to suffer with less security while utilizing the host hypervisors. It is pertinent to mention here that there are few operating systems cannot be installed simultaneously utilizing the hypervisors. The hypervisor technology only supports the Intel operating systems, whereas, the type 1 or native hypervisor does not support Solaris SPARC, AIX, HPUX, and the high-End UNIX systems.
