Host touch device support (GUI passes host touch events to guest)/USB virtualization of such devices.Can automatically run VMs on host system startup (except on Windows hosts).Support for limiting network I/O bandwidth.Support up to 36 NICs in case of the ICH9 chipset.Some VM settings can be altered during VM execution.Virtual machine groups – allows management of a group of virtual machines as a single unit (power them on or off, take snapshots, etc.).Resizing of disk image formats from Oracle, VDI (VirtualBox disk image), and Microsoft, VHD (Virtual PC hard disk).Multi-monitor guest setups for Linux/Solaris guests (previously Windows only).CPU use and I/O bandwidth can be limited per VM. In addition to OVF, the single file OVA format is supported.On 32-bit hosts, VMs can each use more than 1.5 GB of RAM.Several UI enhancements including a new look with VM preview and scale mode.A new VM storage scheme where all VM data is stored in one single folder to improve VM portability.As part of this change, additional components of VirtualBox were made open source (installers, documentation, device drivers) The PUEL/OSE separation was abandoned in favor of an open source base product and a closed source extension pack that can be installed on top of the base product.Run and control guest applications from the host – for automated software deployments.Remote Desktop Protocol (RDP) video acceleration via a non-free extension.Multi-monitor guest setups in the GUI, for Windows guests.Deleting snapshots while the VM is running.CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only).RAM deduplication (Page Fusion) for Windows guests on 64-bit hosts.Memory ballooning (not available on Solaris hosts).Mac OS X Server guest support – experimental.Please relocate any relevant information into other sections or articles. This section contains a list of miscellaneous information. In December 2019, VirtualBox removed support for software-based virtualization and exclusively performs hardware-assisted virtualization. įollowing the acquisition of Sun Microsystems by Oracle Corporation in January 2010, the product was re-branded as "Oracle VM VirtualBox". Sun Microsystems acquired InnoTek in February 2008. Specifically, InnoTek developed the "additions" code in both Windows Virtual PC and Microsoft Virtual Server, which enables various host–guest OS interactions like shared clipboards or dynamic viewport resizing. InnoTek also contributed to the development of OS/2 and Linux support in virtualization and OS/2 ports of products from Connectix which were later acquired by Microsoft. In January 2007, based on counsel by LiSoG, InnoTek released VirtualBox Open Source Edition (OSE) as free and open-source software, subject to the requirements of the GNU General Public License (GPL), version 2. VirtualBox was first offered by InnoTek Systemberatung GmbH, a German company based in Weinstadt, under a proprietary software license, making one version of the product available at no cost for personal or evaluation use, subject to the VirtualBox Personal Use and Evaluation License (PUEL). History Logo of VirtualBox OSE, 2007–2010 The License to VirtualBox was relicensed to GPLv3 with linking exceptions to the CDDL and other GPL-incompatible licenses. Released under the terms of the GNU General Public License and, optionally, the CDDL for most files of the source distribution, VirtualBox is free and open-source software, though the Extension Pack is proprietary software, free of charge only to personal users. For some guest operating systems, a "Guest Additions" package of device drivers and system applications is available, which typically improves performance, especially that of graphics, and allows changing the resolution of the guest OS automatically when the window of the virtual machine on the host OS is resized. It supports the creation and management of guest virtual machines running Windows, Linux, BSD, OS/2, Solaris, Haiku, and OSx86, as well as limited virtualization of macOS guests on Apple hardware. There are also ports to FreeBSD and Genode. VirtualBox may be installed on Microsoft Windows, macOS, Linux, Solaris and OpenSolaris. VirtualBox was originally created by InnoTek Systemberatung GmbH, which was acquired by Sun Microsystems in 2008, which was in turn acquired by Oracle in 2010. Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and InnoTek VirtualBox) is a hosted hypervisor for x86 virtualization developed by Oracle Corporation. GNU GPLv3 only with linking exception to GNU GPLv2 incompatible licenses X86-64 only (version series 5.x and earlier work on IA-32) Windows, macOS (only Intel-based Macs), Linux and Solaris
