* Virtualization requires a compatible processor – not all processors support that feature* Most recent multi-core processors support virtualization* The virtualized OS is installed and run in a window under another OS:*The installation can usually be completed from an ISO image:*One or more virtual machines can be run at the same time The guest OS shares the hardware with the host OS and possibly other virtualized systems:*Special software is used to manage the entire process, this is the “hypervisor”:* The guest systems have network access through the host * The selection of virtualization software (which allows creation and running of virtual machines) depends mainly on the host OS, although some are cross-platform. Other considerations as to virtualization software may be features, support, price and/or personal preferences.
