VMware
Features

VMware creates a virtual computer that cuts no corners on the functions you need. You can share files, send email, and run all your familiar software -- just like your real machine. It's just that this machine lives in its own window.

Installation is a snap. And should a virtual machine crash, everything else will continue without a hitch. To a developer, that means fault isolation. Big time.

In this innovative new world of VMware, you can:

 

	Use all the virtual machines that are necessary. And enjoy the fact that you only need to boot the computer once.
	Employ a number of guest operating systems, ranging from Windows 98 and FreeBSD -- on to a long list of Linux systems.
	Pop in and out of applications across different operating systems -- as you need them. Again, without needing to reboot.
	Enjoy full networking, dial-up access and file-sharing support. Each machine has its own network address, just like a real machine.
	Display your virtual computer as a window -- or in full-screen.
	Suspend your virtual computer to the disk and immediately resume, using Instant Restore.
	Cut and paste between your virtual machines and the host computer.
	Use SCSI disks and CD-ROM drives.
	Hook up your Zip Drive. You've got bidirectional parallel ports.
	And enjoy the music. VMware supports sound input and output.
