VirtualBox 6.0.0

VirtualBox

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 6.0.0 is a major update. The following major new features were added:

Implemented support for exporting a virtual machine to Oracle Cloud Infrastructure
User interface: greatly improved HiDPI and scaling support, including better detection and per-machine configuration
Major rework of user interface with simpler and more powerful application and virtual machine set-up
User interface: a new file manager enabling user to control the guest file system and copy files between host and guest.
Graphics: major update of 3D graphics support for Windows guests, and VMSVGA 3D graphics device emulation on Linux and Solaris guests
Added support for surround speaker setups (as used by Windows 10 Build 1809)
Added utility vboximg-mount on Apple hosts to access the content of guest disks on the host
Added support for using Hyper-V as the fallback execution core on Windows host, to avoid inability to run VMs at the price of reduced performance

In addition, the following items were fixed and/or added:

Execution core: fixed single-stepping in certain circumstances (bug #17316)
User interface: video and audio recording can now be separately enabled
Audio/Video recording fixes and improvements
Audio: better support for attaching and detaching remote desktop connections
Serial port emulation fixes
Serial ports: allow changing the serial port attachment while a machine is running (bug #6115)
Networking: Added a workaround for older guests which do not enable bus mastering for the virtio PCI device
Networking: fixed wrong RCODE from DNS AAAA query with --natdnshostresolver1 (bug #18171)
iSCSI: In cases where there is no ambiguity, the LUN of an iSCSI target is automatically determined, for targets with non-zero LUNs
Transparently resize disk images when merging if possible
VBoxManage: support for DHCP options
Fixed VNC/RDP (bug 18153)
Guest Control: various new interfaces and features (see SDK documentation)
