VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.
Some of the features of VirtualBox are:
- Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don"t have to hack the source to write a new interface for VirtualBox.
- Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
VirtualBox 5.1.20 is a maintenance release. The following items were fixed and/or added:
- GUI: don"t check if the Extension Pack is up-to-date if the user is about to install a new Extension Pack (bug #16317)
- GUI: fixed a possible crash when switching a multi-monitor VM into full-screen or seamless mode
- GUI: fixed non-literal shortcuts if the keyboard is not captured (5.1.10 regression; Windows hosts only)
- GUI: several mini-toolbar fixes in full-screen / seamless mode (X11 hosts only)
- GUI: don"t crash on restoring defaults in the appliance import dialog
- Windows Additions: another fix for automatic logins for Windows Vista and newer (bug #15904)
- ICH9: fix for Windows guests with a huge amount (>64G) of guest memory
