It’s a bit like the theory that we are all just slivers of a greater consciousness living in a dream, believing we are all separate individuals, but really belonging to a greater whole – the dreamer. ![]() A VM is also known as a guest on the host server. So a virtual machine is a computer that is imagined by another computer (the host server). whenever the virtual machine is “turned on” it basically cuts out a part of its own brain and gives it to the VM! For instance – this virtualized hardware takes raw computing power in the form of CPU cores from the server and programmatically makes it operate as if it were a completely independent CPU chipset. Since it can’t create a brand new physical motherboard or computer chip out of nothing, it creates a connection through software pretending to be physical hardware. ![]() To accomplish this, the physical server- called the host– has to not only borrow those basic parts of itself, like CPU cores, RAM and storage (the thinking and remembering parts), but also has to connect those things to make them operate in concert with one another. This is called a virtual machine( VM for us geekier folks). In plainer terms, a virtualization server takes its own hardware- the physical parts of itself- and uses portions of it to create an (almost) completely separate computer inside of itself! No- it doesn’t actually move the hardware around to build another physical computer, but it borrows from in-place hardware and creates a virtual environment for those borrowed pieces to function as one cohesive unit, but separately from its own normal operations. Virtualizationis technically the emulation (to imitate or mimic) of hardware (physical components of a computer) via software (a program or set of instructions). ![]() Okay, not really out of thin air, but it’s still pretty darn magical. Simply put, a virtualization server is a computer that creates other computers… out of thin air! Magic, right? What is a virtualization server? Why would you want to build one? How do I build one? How long does it take? Is it really worth it? Where’s Waldo? These (and many other) questions will be answered in this series… let’s start! What is a Virtualization Server?
