Download VirtualBox 4.0.10

Oracle has released the fifth update to VirtualBox version 4.0 with version 4.0.10. This program can be used to install other operating systems on a computer in a virtual environment. In this way it is possible to use different operating systems on the same hardware. VirtualBox is available for Windows XP and above, Mac OS X, Linux, and Solaris, and is capable of many guest operating systems to turn.

VirtualBox is available in two versions. The full version has additional functionality, such as support for USB ports and the remote display protocol, but is only free for private use and evaluation purposes. The extra functionality is closed source and is therefore not present in the open source version. It may, however, be used in commercial environments, provided you install it yourself on the PC. New in version 4.0 is, among other things, that the program is now offered as a basic package and that it contains extra functionality in separate extension packs. The following changes and improvements have been made in this update:

The following items were fixed and/or added:

• GUI: fixed disappearing settings widgets on KDE hosts (bug #6809)
• Storage: fixed hang under rare circumstances with flat VMDK images
• Storage: a saved VM could not be restored under certain circumstances after the host kernel was updated (bug #8983)
• Storage: refuse to create a medium with an invalid variant (for example Split2G with VDI; bug #7227)
