These virtual machines can share a slice of the host machine's CPU, memory, disk, and other hardware in a way that protects the host machine and other virtual machines from whatever's going on inside a particular VM. Virtualization is often used to make more efficient use of a powerful host's resources enabling one physical server to host a handful, dozens or more of different operating systems each doing their own thing. Cloud providers and other enterprises use virtualization to pack a large number of running systems into a smaller physical space. This works out well because in many cases a system that's running it's normal workload isn't using the full amount of resources available to it. For example a dual-core Xeon machine with 64 gigabytes of RAM isn't using all of that, at least we hope it's not, serving up a…
