How you create a virtual machine depends on its guest operating system.

You can create a virtual machine that uses a Microsoft Windows operating system as its guest operating system.

You can create a virtual machine that uses a Linux distribution as its guest operating system.

You can install Mac OS X Server 10.5, 10.6, 10.7 in a virtual machine. VMware Fusion creates the virtual machine, opens the Mac OS X Server installation assistant, and installs VMware Tools. VMware Tools loads the drivers required to optimize a virtual machine's performance.

You can create a virtual machine with a guest operating system that does not have an Easy Install option if the guest operating system is supported by VMware Fusion.

You can use the contents of your Boot Camp partition at the same time that you are running your Mac operating system. To do so, you use VMware Fusion to power on the Boot Camp partition as a virtual machine.

In some cases you must activate Windows when you create, import, or migrate a virtual machine.
