VirtualBox is a powerful tool that can be used create one or more
virtual machines on a single computer. This can be used for testing
different operating systems or various applications, which can be
installed on them. Virtual Box 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.
Guest Additions for Windows, Linux and Solaris. VirtualBox has special software that can be installed inside Windows, Linux and Solaris virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window). There are also guest additions for OS/2 with somewhat reduced functionality.
Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.
# The following items were fixed and/or added:
- VMM: don't inject stale VT-x events to prevent crashes after VM reset
- VMM: workaround for buggy BIOSes which enable MONITOR only for certain CPUs
- GUI: fixed trimming of anti-aliased text in details-view element headers (4.2.0 regression)
- GUI: fixed create-settings-file-alias functionality on Mac hosts (4.2.0 regression)
- GUI: fixed take-guest-screenshot functionality on Windows hosts
- GUI: several minor fixes, including palette fixes
- GUI: fixed Windows 2012 OS type
- GUI: allow to terminate the VM even if VBoxSVC crashed
- API: fixed cancelling of snapshots, previously this could lead to inconsistent VM configs
- API: fixed identifying disk images by UUID
- 3D Support: several fixes
- VRDP: fixed occasional crash with external authentication
- VGA: fix for double scan text modes
- USB: fixed invalid pending request count at the time of service of DEVICE POWER requests (Windows hosts only)
- USB keyboard: Korean keyboard workaround
- Storage: fixed hang with QCOW images and asynchronous I/O enabled
- Storage: fixed hang with newer VHD images
- Storage: actually write the non-rotational flag to the VM settings (4.2.0 regression)
- Virtio-net: fixed the problem with network statistics counters in Session Information dialog (GUI)
- Metrics: introduced network rate and disk usage metrics
- Metrics: fixed a crash under certain conditions on Solaris hosts
- BIOS: fix for El Torito
- Shared Folders: if the host folder of a shared folder mapping does not exist, keep it active but mark it as invalid to prevent inconsitent saved states
- VBoxManage: fixed converting disks from raw images
- VBoxManage: show snapshot description in the VM or snapshot information
- VBoxManage: make implicit opening of media consistent in all places dealing with media
- VBoxManage: the iSCSI initiator name was not stored in the settings file when doing storageattach
- VBoxManage: metrics collect now properly handles 'CPU/MHz' and 'Net/*/LinkSpeed' metrics
- VBoxManage: changing the image UUID or parent UUID as part of storageattach works now in all safe cases
- VBoxManage: introduced storageattach --medium additions as a shortcut to mount the additions image
- OVF: fixed importing OVF files cerated by recent VMware products
- Linux hosts / Bridged Networking: fixed the problem with leaking connections in conntrack
- Linux Additions: added support for ConsoleKit sessions in the vminfo service of VBoxService
- Linux Additions: don't crash during remount under certain conditions
- Linux/Solaris Additions: fixed guest memory metrics collection
- Solaris hosts: added a dependency to ensure that the user directories are reachable when starting VBox services
- Windows host installer: integrated user-contributed translations, thanks to all contributors!
- Windows Additions: fixed auto-logon installation for Windows 8
- Windows Additions: don't fail if the shared folders host service is not available
- Windows Additions: fixed Guest Additions startup on Windows 2000 guests
- Windows Additions: auto-resize fixes for Windows 8 guests
