HTG Explains: What is a Virtual Machine Hypervisor? Hypervisors are what make virtual machines possible, and they aren’t just for servers anymore. You probably use one every day and don’t even know it. If you don’t use one now, you will in the near future. A hypervisor is software that exists outside of a guest operating system to intercept the commands sent to the computer hardware. The term “hypervisor” comes from the different levels of an operating systems kernel; it performs actions with more authority than the “supervisor” level, hence, hyper-visor. Image via striatic on Flickr Hypervisor Basics A hypervisor is also known as a Virtual Machine Manager (VMM) and its sole purpose is to allow multiple “machines” to share a single hardware platform. The hypervisor separates the operating system (OS) from the hardware by taking the responsibility of allowing each running OS time with the underlying hardware. Separating hardware and software turns out to be good for portability as well. Different Hypervisor Types Hypervisors of the Future
Difference between vSphere, ESXi and vCenter There is a lot of buzz of VMware virtualization solution these days. No doubt that VMware is the number one virtualization solution provider in the industry. People who are new to VMware’s virtualization platform often get confused while learning VMware vSphere and its components. VMware Inc. is a software company that develops many suites of software products specially for providing various virtualization solutions. vSphere is a software suite that comes under data center product. vSphere is like Microsoft Office suite which has many softwares like MS Office, MS Excel, MS Access and so on. ESXi, vSphere client and vCenter are components of vSphere. vCenter server is similar to vSphere client but it’s a server with more power. vCenter server is installed on Windows Server or Linux Server. You can install vSphere in your PC to get more knowledge of this amazing technology. The following two tabs change content below.

What is VMWare? From the "About Us" page of the VMWare company website: VMware was founded in 1998 to bring virtual machine technology to industry-standard computers. More than 4 million users and over 20,000 corporate customers of all types and sizes use VMware software, including 99 of the Fortune 100 companies. VMWare is widely regarded to be the leader in the virtualization marketplace, and many corporate users are no doubt excited to have the company developing a virtualization solution for MacOS X. What is a "Virtual Appliance"? In the Virtual Appliance Marketplace, VMWare states that: A virtual appliance is a pre-built, pre-configured and ready-to-run software application packaged with the operating system inside a virtual machine.
www.howtogeek Virtual machines allow you to run an operating system in an app window on your desktop that behaves like a full, separate computer. You can use them play around with different operating systems, run software your main operating system can’t, and try out apps in a safe, sandboxed environment. There are several good free virtual machine (VM) apps out there, which makes setting up a virtual machine something anybody can do. You’ll need to install a VM app, and have access to installation media for the operating system you want to install. What’s a Virtual Machine? A virtual machine app creates a virtualized environment—called, simply enough, a virtual machine—that behaves like a separate computer system, complete with virtual hardware devices. In the VM world, the operating system actually running on your computer is called the host and any operating systems running inside VMs are called guests.

Hypervisor 101: Understanding the Virtualization Market Over the past decade, virtualization technologies have gone from small shop and educational tools to full blown IT solutions. In the past, many major software vendors would explicitly say that their software will not work in a virtual state and will not be supported if the end-user decided to virtualize. Now, the technology has changed and evolved. Some of the biggest software makers are now creating design and best practices around a virtual infrastructure. The modern hypervisor: A high-level explanation The evolution of virtualization greatly revolves around one piece of very important software. Type I Hypervisor. Now that there is a better understanding of the hypervisor and the various components which fall under it, we can examine the major players in the industry. The “Big Three” Hypervisor Vendors Although there are several smaller organizations which are developing their own hypervisor technologies, three manufacturers have really taken the market by storm with their solutions.
