VirtualBox 7.0 Beta 1

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 7.0 Beta 1 changelog:

Audio recording: Now using Vorbis as the default audio format for WebM containers. Opus is no longer being used.
Audio: Added “default” host driver type to make it possible to move VMs (appliances) between different platforms without the need of changing the audio driver explicitly. When the “default” driver is selected, the best audio backend option for a platform will be used. This is the default for newly created VMs.
Guest Control: Implemented initial support for automatic updating of Guest Additions for
Linux guests
Guest Control: Implemented ability to wait for and/or reboot the guest when updating Guest Additions via VBoxManage
VBoxManage: Added Guest Control “waitrunlevel” sub-command to make it possible to wait for a guest to reach a certain run level
Windows hosts: Added experimental support of running autostarted VMs in session 0, to allow running VMS even when a usser is not being logged in (disabled by default, please consult the manual)
