VMware Fusion running Windows 7 on Mac OS X 10.6
|Stable release||3.0.2 (build 232708) / February 18, 2010|
|Operating system||Mac OS X|
VMware Fusion is a virtual machine software product developed by VMware for Macintosh computers with Intel processors. Fusion allows Intel-based Macs to run x86 and x86-64 "guest" operating systems, such as Microsoft Windows, Linux, NetWare and Solaris as virtual machines simultaneously with Mac OS X as the "host" operating system using a combination of paravirtualization, emulation and dynamic recompilation.
Fusion is VMware's first entry into the emerging Macintosh x86 virtualization market, which has been made possible by the Apple–Intel transition. Fusion utilizes Intel VT present in the Intel Core microarchitecture platform. Much of the underlying technology in Fusion is inherited from other VMware products, such as VMware Workstation, allowing Fusion to offer features such as 64-bit and SMP support from the first beta version onward.
Fusion 1.0 was released on August 6, 2007, exactly one year after being announced.
Unity view creates a seamless desktop environment between Microsoft Windows and Mac OS X applications. It optionally hides Windows' start menu and taskbar and runs the Windows applications directly from the dock in OS X. Further, users can drag and drop files between Windows and the Mac, and use familiar Mac keyboard shortcuts to copy and paste between Windows and Mac applications. It is (almost) fully compatible with Exposé. Fusion windows that are covered by other Fusion windows don't redraw when switching to Exposé, causing visual anomalies. This feature is later made available in VMware Workstation 6.5 Beta, which is designed to be run on Windows/Linux platforms.
Direct X 9.0 is supported through dynamic recompilation to OpenGL instructions in Windows XP Service Pack 2, Windows Vista, and Windows 7 virtual machines. Hence, users can play supported games through Fusion or run applications which require 3D graphics. VMware Fusion 3 has DirectX 9 Shader Model 3 and OpenGL support.
32-bit and 64-bit guest operating systems are supported by VMWare Fusion.  Over 60 operating systems are supported, including Windows Vista, Windows XP, Linux, and Solaris. Additionally, VMWare Fusion 2.0 adds support for Mac OS X Server version 10.5 (Leopard) as a guest on a Mac OS X host. Additionally, Fusion 2.0.1 added experimental support for un-released developer builds of Mac OS X Server 10.6 (Snow Leopard) - presumably for software developers with Apple-granted access to pre-release builds of Snow Leopard. There is also support for Windows XP Service Pack 2 Boot Camp partitions: a user can use his Windows Boot Camp partition, eliminating the need for two separate Windows installations. In addition, VMWare Fusion offers support of up to 8 GB of memory on guest 64-bit operating systems, and up to 16GB of RAM on Mac Pros and Xserves. 
Snapshots enable users to save a stable state of the guest operating system to disk, allowing users to quickly return to their virtual machine without the need of rebooting.
Shared Folders allow the mounting of folders from the host operating system to the guest operating system.
Extensive hardware support is built into VMWare Fusion. For networking, there is support for wired and wireless networks, in NAT or bridged mode. There is access to physical devices from the virtual machine (i.e. read and write CDs and DVDs) as well as access to USB 2.0 devices such as video cameras, iPods, printers, and disks at full speed. Firewire support is still missing in the latest version, although a workaround exists by mounting the device as a shared folder .
Support for multiple CPUs (SMP) or multicore CPUs is built into VMWare Fusion. Fusion also allows the user to assign up to four CPUs to one virtual machine to gain additional performance for CPU-intensive workloads .
VMware Fusion 2.0 was released as a free upgrade on September 12, 2008. New features in this release include:
