Among the features for VirtualBox 4.1 are
PCI pass-through support,
many fixes, GUI enhancements, an experimental Windows WDDM graphics driver, experimental support for Serial ATA hot-plugging, and much more. A
detailed change-log is available for those interested.
VirtualBox 4.1 for Linux, Windows, Mac OS X, and Solaris is available from
