Chillopedia.com | It’s true that virtual machines (VMs) aren’t what they used to be, but that may be a good thing. Back in the days of desktop virtualization, VM users would be forced to use two separate partitions to run two separate operating systems side-by-side. This would require unnecessarily demanding computing resources. For instance, if you were running Linux and Windows on your machine, switching between operating systems meant signing out of one VM and into the other. This not only delayed IT efforts, but also required processing power that slowed down in-house computing resources.
