VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2. See “About VirtualBox” for an introduction.
Presently, VirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7, Windows 8, Windows 10), DOS/Windows 3.x, Linux (2.4, 2.6, 3.x and 4.x), Solaris and OpenSolaris, OS/2, and OpenBSD.
VirtualBox is being actively developed with frequent releases and has an ever growing list of features, supported guest operating systems and platforms it runs on. VirtualBox is a community effort backed by a dedicated company: everyone is encouraged to contribute while Oracle ensures the product always meets professional quality criteria.
This is a major update. The following major new features were added:
- Virtualization core: fixed performance issue observed with Windows XP guests on AMD hosts (6.0.0 regression; bug #19152)
- Virtualization core: consistent IBRS/IBPB CPUID feature reporting, avoids crash of NetBSD 9.0 RC1 installer (bug #19146)
- GUI: fixed updating of runtime info
- GUI: in Display settings, do not show “2D video acceleration” checkbox if it is meaningless for the selected graphics adapter
- Audio: fixed audio input handling when VRDE is enabled
- Audio: fixed crash in the HDA emulation when using multi-speaker configurations
- Storage: fixed use of encrypted disks with snapshots involved (6.1.0 regression; bug #19160)
- Storage: improve performance of virtio-scsi
- Storage: read-only support for compressed clusters in QCOW2 images
- Windows installer: include unintentionally dropped vbox-img.exe utility again
- Windows host: when installing or removing an extension pack, retry the sometimes failing directory renaming (usually caused by anti-virus software accessing the directory)
- Linux host: Support Linux 5.5 (guest additions not yet)
- Windows guest: accelerate 2D video decoding (scaling and color space conversion) if the VM is configured to use VBoxSVGA with 3D enabled
- Windows guest: fix guest additions installer to upgrade the mouse filter driver reliably
- Windows guest: when uninstalling older Guest Additions with old 3D support enabled try restoring original Direct3D files
- Linux guest: improve resize and multi-monitor handling for VMs using VMSVGA (known remaining issue: do not disable a monitor “in the middle”, causes confusion)
