In this course Martin Guidry explores the crucial concepts behind today's virtualization tech, its pros and cons, common uses, and hardware requirements. Virtualization no longer needs to be a distinct layer of the IT stack that has to be licensed, deployed, and managed separately. Starting with Windows 8 , Hyper-V superseded Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. Simply put a virtual machine is a computer within a computer. This tool helps to determine the number and estimate the cost of software and hardware components for a given virtualization environment. Spreading up into six areas of IT, virtualization is here to stay to ease out IT management. Nested virtualization adds support for Intel VT-x processor virtualization instructions to Compute Engine VMs. Upstream, a Virtual Switch can be used by a VMkernel Port, Virtual Machine Port or Service Console Port. And of course if anyone has a link to any documentation of how to do what I want, that would be greatly appreciated. It involves compiling multiple physical hard drives into a single virtualized storage environment. Conversely, hosted virtualization utilizes an operating system and runs virtualization software as an application. In order for type 1 to work, special hardware requirements are required. The open-source KVM (or Kernel-Based Virtual Machine) is a Linux-based type-1 hypervisor that can be added to most Linux operating systems including Ubuntu, Debian, SUSE, and Red Hat Enterprise Linux, but also Solaris, and Windows. It refers to the concept of the creation of an abstraction layer in between the actual physical hardware resource and the software application.
