Specialized software called a hypervisor emulates the PC client or server's CPU, memory, hard disk, network and other hardware resources completely, enabling virtual machines to share the resources. Virtual machines do not require specialized hypervisor-specific hardware. Margaret Rouse asks: VMware vs. Oracle VM | Virtual Machine. 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. Matching the needs of the industry to create a more efficient infrastructure – virtualization was re-born as a powerful platform. Some of the biggest software makers are now creating design and best practices around a virtual infrastructure.
The industry has shifted from 1-to-1 hardware platforms and has created a more efficient data center in which resources are shared between numerous workloads. The modern hypervisor: A high-level explanation The evolution of virtualization greatly revolves around one piece of very important software. Type I Hypervisor. The “Big Three” Hypervisor Vendors.

Once you understand virtual machines (VMs) from a hardware perspective, you can study the components that make up a VM on an ESX/ESXi host. VMware virtual machine files are organized in the Virtual Machine File System (VMFS). So what are all these VMware file types and what are they used for? The .nvram file. The .vmx file. VMDK files.

Hypervisor products from the major virtualization vendors have their pros and cons, so consider the features of these hosted and bare-metal virtualization hypervisors before you make your decision. Bare-metal virtualization hypervisors VMware ESX and ESXi VMware has the most mature hypervisor technology by far, offering advanced features and scalability.
Microsoft Hyper-V Microsoft Hyper-V has emerged as a serious competitor to VMware ESX and ESXi. 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. Virtualization Products for Virtual Servers, Virtual Desktops, and Data Center. vSphere Documentation Center.
