Join Jon Peck for an in-depth discussion in this video Introducing system virtual machines with VirtualBox, part of Learning Linux for PHP Developers.
…Linux is really useful, but it needs to be installed somewhere.…Most people, including myself, don't have a spare…computer lying around to use as a development server.…This is where virtual machines come in.…A system virtual machine, or VM for short, is the complete software emulation of…a physical computer system, meaning its functionality…is equivalent to whatever it's acting like.…A VM allows an entire operating system to run normally within it…and the operating system thinks that it's installed on a regular computer.…A VM typically emulates an existing hardware system,…such as the architecture found in desktop PCs.…
Using this software, you can run multiple operating…system environments on a single computer, even simultaneously.…This allows you to do things like run a…copy of Windows XP within a VM within Mac OS.…This can be incredibly useful for testing or using platform specific software.…Think of it like a matryoshka stacking doll,…where the smaller doll is within a bigger doll.…So what manages the virtual machines?…
The demonstrations are performed with the Ubuntu LTS distribution of Linux, but the skills taught here are also applicable to other Linux distributions. Every command is described in detail in context, and a comprehensive quick reference is provided for convenience.
