Head to Head: Parallels Desktop 7 vs VMware Fusion 4

The two leading virtualisation programs for the Mac have both been updated. Are they essentially identical or is one definitively better than the other? Julian Prokaza pits them against each other to find out.

Creating a new virtual machine

Parallels Desktop 7 has the edge when it comes to getting started with a new virtual machine, at least in terms of user friendliness. Clicking its new' button opens a dialog box with clearly presented options for creating a new virtual machine. If an install disc or image is supplied, the OS is detected and a new virtual machine configured with its recommended specification although this can be customised before installation begins. Alternatively, the OS can be selected manually all versions of Windows from 3.11 onwards are supported, along with several Linux distros, Mac OS X and Chrome OS.

Both Parallels Desktop 7 and VMWare Fusion 4 also support downloadable 'virtual appliances'.

VMWare Fusion 4 assumes rather more knowledge on the user's part when it comes to setting up a new virtual machine. Clicking the create new' option on its sparse virtual machine manager window simply prompts for an OS installation disc or image, or for the OS to be chosen from a longer list than that in Parallels Desktop 7. As with Parallels Desktop 7, both options result in an appropriately preconfigured virtual machine. Fusion 4 doesn't allow a new virtual machines specification to be customised until after it has been created and the OS installed, though.

Both Parallels Desktop 7 and VMWare Fusion 4 also support downloadable 'virtual appliances' preconfigured guest systems that include a diverse range of operating systems, database servers, mail servers and other useful set-ups that would otherwise be time consuming or impractical to configure. Parallels Desktop 7 puts direct download links to three (Chrome OS, Fedora and Ubuntu) in its new machine dialog box, but otherwise makes no mention of them elsewhere in the application and it's left to the user to figure out where a much bigger selection can be found online. VMWare Fusion 4 has no direct download links, but does tuck away a download virtual appliances' option in its File menu.

Winner: Parallels Desktop 7 for its very user friendly wizard for creating new virtual machines.
