We expect virtualisation isn’t anything new to you, our happy reader, but it’s a topic that’s constantly evolving, improving and has become essential to a world that expects the ability to spin up multiple instances remotely in seconds. So this issue we’re holding your hand and taking you through the vital basics of creating a VirtualBox, getting more from managed snapshots to newer Docker Containers and cutting-edge development of GPU passthrough. So by the end of this issue you should feel you know your KVMs from your kernel chroots.
Even if you’re just using VirtualBox to keep a sneaky install of Windows hidden away (admit it, you know it’s true), the copious amounts of storage and computing power that even a modest PC offers can happily cope with storing and running multiple instances. It’s just a matter of knowing the best approaches, and is another fine example of how open source technologies have come to rule this admittedly virtual world.
