You can create a virtual machine that uses a Linux distribution as its guest operating system.
Fusion creates your virtual machine, selects the default Linux installation options, and installs VMware Tools, which loads the drivers required to optimize your virtual machine's performance. You can also have Linux Easy Install make your home folder available to Linux as a shared folder, so that you can share files between the virtual machine and your Mac.
Linux Easy Install is available for the following operating systems:
Ubuntu 7.10 and later
Ubuntu Server Edition 8.10 and later
Red Hat Enterprise Linux 3 and later
SUSE Linux Enterprise Desktop/Server 10 and later
Open SUSE 11.3 and later
If you are not using one of these Linux operating systems in your virtual machine, or if you are using Linux but want to install the operating system manually, you can use the procedure for creating a virtual machine for any supported operating system.
