Virtual machines are virtually taking over the world. By itself a virtual machine is just a container that describes various resources such as memory, disk space, processor, and network card, and allocates them from a physical machine. As with a physical machine, it's the software bits (the operating system and applications) that make a virtual machine usable.

The Linux memory management code does its best to ensure that memory will always be available when some part of the system needs it. That effort notwithstanding, it is still possible for a system to reach a point where no memory is available.

A virtual machine creates a virtual hard drive as well as a virtual computer, so you can install and run it from within another operating system. If you want to get rid of the virtualized (also known as the guest) operating system, just delete the virtual hard disk from the real (host) computer’s hard drive.

"Software developers seem largely incapable of understanding the difference between resources and their representation. Understanding that difference is absolutely vital in understanding REST and the Resource Oriented Architecture (ROA).[...]Understanding this distinction is vitally important if we are to move forward successfully in building the functional web of information..."

VMware Tools is a suite of utilities that enhances the performance of the virtual machine’s guest operating system and improves management of the virtual machine.Installing VMware Tools in the guest operating system is vital.

It's something of a tradition that we pit the latest version of Windows against our trusty old operating system. This isn't because we want to raise the profile of Windows, or ignite further flamewars on which is better or worse. It's about understanding the market and understanding the competition.

Get an introduction to swap (paging) space, learn how to configure and administer it, capture statistics, and tune your Virtual Memory Manager (VMM) settings to provide for optimum swap (paging) space configuration and performance.

The definition of virtual Linux is as fluid as the Linux platform itself. For the desktop user, virtual Linux translates into being able to use Linux without changing their existing operating system. For those working with servers however, virtual Linux can mean something very different altogether.

Text plays a central role in the Linux operating system. Take better control of your system with a firm understanding of what text is and how best to handle, format and convert it.
