Virtualization hardware

Allows to run multiple operating systems on single computer

Isolates each operating system from others Allows to work on different platforms at the same

time Allows migration of virtual machines

WHY? Save finance on hardware Save energy and nature Protect main operating system from untrusted

software Work with different operating systems concurrently All the cool kids are doing it
