VirtualBox 6.1.2

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 6.1.2 changelog:

  • 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)
