SMP-Enabled Sun xVM VirtualBox 3.0 Turns Up the Heat on VMware
Version 3.0 of Sun's xVM VirtualBox desktop virtualization tool adds support for multiple guest processors--a major feature addition that, when considered alongside the product's low cost (free) and broad host platform support, is certain to give VMware Workstation a run for its money.Sun Microsystems' xVM VirtualBox, a no-cost virtualization tool that enables virtual machines to run on a variety of standard operating systems, continues to improve its position as a potential challenger to workstation products from VMware and Parallels. Sun released Version 3.0 of xVM VirtualBox on June 30 and added symmetric multiprocessing (SMP) as the major new feature.
I tested VirtualBox 3.0 on a Sun Fire x4170 server running Windows Server 2008 64-bit and equipped with 12GB of RAM and two quad-core Intel Xeon x5570 "Nehalem" processors. On this machine, I was able to create guests with up to 16 virtual CPUs by taking advantage of hardware-enabled hyperthreading. I also tested it on a Lenovo T400s laptop running Windows Vista and equipped with an Intel Centrino Core 2 Duo CPU and 2GB of RAM, and on a Mac mini running OS X to run Windows XP. http://www.virtualbox.org/wiki/Changelog. In addition to Windows and OS X, VirtualBox supports Linux, Solaris and OpenSolaris as host operating systems. VirtualBox is available for free download at http://www.virtualbox.org/wiki/Downloads.
