Linux virtualization refers to running one or more virtual machines on a physical computer that’s operated by the Linux open source operating system. Linux virtualization can be used for isolating specific apps, programming code or even an operating system itself, as well as for security and performance testing purposes.

Powerful computers and hardware have made virtualization more practical and feasible for both desktop and server environments, helping to save power by consolidating several workspaces on one system as well as maximizing the workload that the compute can handle. Popular Linux virtualization solutions include Xen, KVM, QEMU, VirtualBox and VMware.
