Summary:  This tutorial shows how to install, configure, and use Linux® virtual machines. With User-Mode Linux (UML), you can set up multiple virtual machines that are isolated from each other and from the hardware. This lets you test applications all the way to failure without breaking the host system -- or even requiring a reboot.

About this tutorial

Ever wish you had a place to let your Linux applications play -- where they wouldn't hurt anything else? Do your killer apps spend too much time killing each other? Originally conceived as a kernel developer's tool, UML lets you set up multiple virtual machines that are isolated from each other and from the hardware. Now, you can test applications all the way to failure without breaking the host system -- or even requiring a reboot. Veteran administrator Carla Schroder shows you how.
