VMware Virtualization

The concept of virtualization started as early as 1960s but it was only widely used today. The old days require software and hardware components in order to create virtual machines. But now, virtualization is a different term. A simple example of virtualization process is the creation of hard disk partition. Virtualization can be used for both hardware and software and is very helpful for cost-cutting while using better computer system. One can even use software applications which can be very helpful for computer virtualization.

Virtualization is a method that enables installing and running multiple operating systems and their applications on a single hardware platform (Piltzecker, 2008). This form of abstraction enables the consolidation of diverse environments while allocating the hardware resources as desired between the virtual machines hosting the guest operating systems. Virtualization can be realized with software solutions from VMware, Microsoft, or the open source alternative Xen, with all alternatives supporting the installation of Linux operating systems.

Some server platforms also offer enhancements to software-based virtualization by providing features such as hardware-based memory protection, hardware-based translation between virtual machines and operating systems, and differing levels of privilege over hardware resources. Virtualization provides the ability to create and host multiple machines within one physical machine, thereby allowing the development of complex scenarios with a minimal hardware commitment. It includes the ability to create standard configurations for virtual machines, which can then be essentially cloned and used by others.

VMware is among the many applications available today for computer virtualization. It is actually one of the earliest software in this field. VMware can also be used easily by anyone. Some applications may require technical knowledge but VMware is a simple application. One can use VMware or other virtualization software to create his virtual computers. There are a lot of benefits from computer virtualization. The simple partitioning of hard disk proves to be very helpful for individuals in saving disk space and improving the performance of his computer.

Aside from this, computer virtualization is also helpful if one wants to have two or more operating systems in one physical computer. This is great news for students or software vendors who frequently work with various operating systems. Not only can a set of notebook or desktop be created with their virtual counterparts but even servers can be created with a computer machine. VMware and other virtualization software are very helpful for this. One would not need many physical computers just to create a network. Only one computer is needed to represent all the virtual machines.

Computer virtualization can really help everyone save money, time, and space. VMware is not ideal for performance testing as any one individual virtual machine is not aware that it is sharing resources with both other virtual machines as well as the host system (Rossbrg, 2006). MVware virtualization allows moving a VM while running from one piece of hardware to another, giving you the ability to scale and manage peak loads without the cost of idle hardware. You can even automate the load balancing and server utilization for 100% uptime.

On the other hand, a commonly associated use of virtualization for RAC is the ability to install multiple nodes of the same cluster into virtual machines on the same hardware platform, thereby realizing a cluster configuration on a single server. Virtualized images can also enable the rapid provisioning of RAC environments. Virtualization is of increasing importance to RAC and worth the time invested keeping up to date in developments of the technology. VMware software has become very popular with system administrators worldwide (Smith & Nair, 2005).

This is especially the case with NetWare administrators, because VMware is the only virtualization product that supports NetWare as a guest operating system. VMware’s revenues have reached nearly $1B in less than 10 years since its founding. Can the company maintain its dominance of the virtualization software market or will Microsoft, open source and/or others prove that their glory days are now? It’s clear that VMM/Hypervisor is a piece of technology that is rapidly becoming a commodity and is potentially also an interesting candidate for being 100% in hardware.

Given this it seems clear that virtualization vendors that will be successful long term are those who are VMM/hypervisor agnostic and who have diverse virtualization technologies. VMware is still in the lead in this regard. They are clearly working to create value above and around the actual virtualization layer. Long term this is where most of the value for all virtualization players will be created. VMware has ‘gets it’ and has been moving quickly in front of their competitors towards this goal.

Whispers from inside the walls of VMware tell they are going so far as to consider making ESX server type functionality free or nearly free in the not so distant future (think:post-IPO). This is an effective means for beating Microsoft to the punch and they clearly have enough leverage in other software and support services to pull it off in a way that means business. Meanwhile, the process of installing VMware tools relies on Windows version. The newer Windows versions require more automated procedures. For Windows XP guest, the following are the steps to follow: First, the virtual machine should be powered on.

Prepare the virtual machine in the installing process of VMware tools when guest operating system has begun. In the File menu, choose Install VMware Tools. The next steps will be done by the virtual machine. If the auto run is enabled in the guest operating system, the dialog box will appear after few seconds. It will ask if the VMware tools should be installed. Then click the yes button and the Install Shield Wizard will be launched shortly. However, if the auto run is disabled in the operating system, the dialog box will not automatically appear.

Run the installer of VMware tools by clicking the start menu and choose run. In the run command bar, type D:\setup\setup. exe where drive D: is the initial virtual CD-ROM. There is no need for actual CD-ROM in order to install the VMware tools. The CD-ROM does not also need to be downloaded or to be burnt since the software of VMware workstation already contains the ISO image. The image is similar to the CD-ROM in the guest operating system and in the windows explorer. All the needed files for installing VMware tools in guest operating system are contained in the ISO image.

After successfully installing VMware tools, the image file disappears in the CD-ROM drive. For the final step, simply follow on-screen instruction. For Windows XP gust and Windows 2000, there is no need to reboot because the new diver is ready to be used. VMware Inc. produced virtual machine software for Macintosh computers that come with Intel processors known as VMware fusion. Fusion basically fused a clean and sensitive interface that goes with a platform of virtualization reason why this is trusted by numerous users ( Von Hagen, 2007).

Thorough the aid of the advanced virtualization technology, it is now easy for one to control the entire hardware available on Mac through the use of Vmware fusion.
