VirtualBox is a full x86 hardware virtualizer, suitable for server, desktop and embedded usage. It's extremely feature-rich, emulates lots of individual and alternative hardware and devices, supports different virtual machine disk formats, it's cross-platform and supports ancient and current Windows versions, DOS systems, BSD, Solaris and OS/2 as guest operating system.
minor feature: Implemented support for importing a virtual machine from Oracle Cloud InfrastructureExtended support for exporting a virtual machine to Oracle Cloud Infrastructure, allowing the creation of multiple virtual machines without re-uploading. Also added option to export a VM to the cloud using the more efficient variant "paravirtialized", and to specify free-form tags for cloud images.Virtualization core: Support for nested hardware-virtualization on Intel CPUs (starting with 5th generation Core i, codename Broadwell), so far tested only with guest running VirtualBox.Graphics: New style 3D support (with VBoxSVGA and VMSVGA) remains, old style 3D support (with VBoxVGA) has been completely removed.Shared Clipboard: Implemented experimental support for file transfers (Windows hosts/guests only at the moment). Needs to be enabled via VBoxManage.In addition, the following items were and/or added:Virtualization core: Drop recompiler, i.e. running VMs now needs a CPU supporting hardware virtualization.Runtime: Works now on hosts with many CPUs (limit now 1024).Appliance and Cloud Import: Add field for defining firmware type (not part of OVF spec and thus manual in the Appliance case, for OCI it is automatically taken from the instance information).GUI: Improved the VISO creation and file manager dialogs.GUI: Virtual machine list of VirtualBox Manager was improved. Machine groups are now more obvious visually and VM search functionality has been improved. Global Tools element can now be pinned in place, to avoid scrolling it with rest of machine list.GUI: Virtual machine details pane is now extended with embedded editors for selected VM attributes, allowing user to edit them on-the-fly byi clicking corresponding hyper-links without opening VM settings dialog.GUI: Details pane provides more complete information.GUI: Internal medium enumeration routines were optimized to reduce the load and optimize the performance in cases when user have lots of media registered.
