“The new release represents a culmination of hundreds
of bugfixes and significant performance enhancements, including the
ability for the product to permit guest OSes to use up to 32
virtual CPUs each. Under previous versions of the product, only one
CPU core per guest OS was permitted.“With the “Guest Additions” CD accompanying the release,
VirtualBox 3.0 provides full integration for even the most recent
Microsoft OSes, including 32-bit and 64-bit versions of Windows 7
and Windows Server 2008 R2, as well as for all of the major Linux
distributions (Fedora/RHEL, SLES/OpenSUSE, Ubuntu, Debian and
TurboLinux) and Sun’s own Solaris and OpenSolaris operating
systems”
