SUMMARY
A virtual hosting environment lets you run multiple guest operating systems on a single host computer at the same time. Host software virtualizes resources that include the following:
- CPU
- Memory
- Disk
- Network
- Local devices
By virtualizing these resources on a physical computer, host software lets you use fewer computers to deploy operating systems for test, for development, and in production roles. However, certain restrictions apply to the deployment of Active Directory domain controllers that run in a virtual hosting environment. These restrictions do not apply to a domain controller that runs on a physical computer.
