on which a guest operating system and associated application software can run.

One OS can host another Windows Vista on Solaris DOS / Win98 on Linux

Multiple VMs can run on a single host Often have snapshot / restore

VirtualBox VMWare Parallels VirtualPC

VirtualBox Example

VMs in the Development Phase

Virtual Machines Assist With: Multiplatform development / support Network Emulation Creating / maintaining / deploying a

standard development image

Virtual Machines and I&T Conveniently run software tests against

a wide variety of OSes Snapshot / rollback for repeatable tests

and reproducible results Provides capability to have a

deployment dry-run on client OS image
