VMware Workstation vs. VirtualBox vs. Parallels
snydeq writes "InfoWorld's Randall Kennedy takes an in-depth look at VMware Workstation 7, VirtualBox 3.1, and Parallels Desktop 4, three technologies at the heart of 'the biggest shake-up for desktop virtualization in years.' The shake-up, which sees Microsoft's once promising Virtual PC off in the Windows 7 XP Mode weeds, has put VirtualBox — among the best free open source software available for Windows — out front as a general-purpose VM, filling the void left by VMware's move to make Workstation more appealing to developers and admins. Meanwhile, Parallels finally offers a Desktop for Windows on par with its Mac product, as well as Workstation 4 Extreme, which delivers near native performance for graphics, disk, and network I/O. 'There's some genuine innovation going on, especially in the areas of hardware support and application compatibility,' Kennedy writes. 'All support 32- and 64-bit Windows and Linux hosts and guests, and all have added compelling new VM management capabilities, ranging from automated snapshots to live VM migration.'"
It does not do accelerated 3d. That is clearly one of the main features for 'normal' users trying to play games in their VM.
Right, 2nd place because of cost alone:
With support for up to 32 virtual CPUs per VM, VirtualBox is now the class leader in terms of raw virtualization muscle. The introduction of branched snapshots is a major usability upgrade from version 3.0, while the new Teleportation feature (live VM migration) means that VirtualBox is now poised to challenge VMware and Microsoft in the datacenter.
