VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich. Download VirtualBox ¶. Here you will find links to VirtualBox binaries and its source code. VirtualBox binaries ¶. VirtualBox is a general-purpose full virtualizer for x86 hardware, targeted at server, desktop and embedded use.

Version 5.


A supplementary package, under a proprietary license, adds support for USB 2. It virtualbox closed-source components, so it is not source-available. It allows gratis access for personal use, educational use, virtualbox, and evaluation. Virtualbox full package was offered gratis under virtualbox PUEL, virtualbox licenses for other virtualbox deployment purchasable from Oracle.

This removed the virtualbox proprietary software quality engineer not available virtualbox GPLv2, virtualbox, virtualbox, virtualbox.


However, virtualbox, virtualbox, macOS's virtualbox user license agreement does not permit running on non-Apple hardware.

All Apple machines virtualbox an SMC, virtualbox. Each guest can be started, virtualbox, virtualbox, paused and stopped independently within its own virtual machine VM, virtualbox, virtualbox. The user can independently configure each VM and run it under a choice of software-based virtualization or hardware assisted virtualization if the underlying host hardware supports this, virtualbox, virtualbox.

The host Virtualbox and guest OSs and applications can communicate with each virtualbox through a number virtualbox mechanisms including a common clipboard and a virtualized network facility, virtualbox, virtualbox. Virtualbox VMs can also directly communicate with each other if configured to do so, virtualbox. Making use of these facilities, VirtualBox can run each guest VM in its own separate address-space; the guest OS ring 0 code runs on the host at ring 0 in Virtualbox non-root mode rather than in ring 1, virtualbox.

It thus supports disks created by virtualbox hypervisor software. VirtualBox can also connect to iSCSI targets and to virtualbox partitions on the host, virtualbox, virtualbox, using either as virtual hard virtualbox. A special virtualbox network adapter virtualbox also available, which improves network performance by eliminating the need to match a specific hardware interface, but requires special driver support in the virtualbox. Many distributions of Linux virtualbox with virtualbox driver included, virtualbox, virtualbox, virtualbox.

Bridged networking via a host network adapter or virtual virtualbox between guests can also be configured. Up to 36 network adapters can be attached simultaneously, but only four are configurable through the graphical interface, virtualbox. The proprietary extension pack adds a USB 2, virtualbox, virtualbox, virtualbox. This mode supports bit guest OSs which run in rings virtualbox and 3 of virtualbox Intel ring architecture, virtualbox, virtualbox.

The system reconfigures the guest OS code, which virtualbox normally run virtualbox ring 0, virtualbox, to virtualbox in ring 1 on the host virtualbox. Because this code virtualbox many privileged instructions which cannot run natively in ring 1, Virtualbox employs a Code Scanning and Analysis Manager CSAM to scan the ring 0 code recursively before its first execution to identify problematic instructions and then calls the Patch Manager PATM to perform in-situ patching, virtualbox.

This replaces the instruction with a jump to virtualbox VM-safe virtualbox compiled code fragment in hypervisor memory, virtualbox. The guest user-mode code, virtualbox, virtualbox, virtualbox, running in ring 3, virtualbox, virtualbox, virtualbox, virtualbox, virtualbox, generally runs directly on the host hardware in ring 3, virtualbox, virtualbox.


VirtualBox also virtualbox a virtualbox recompilervirtualbox, based on QEMU to recompile any real mode or protected mode code entirely e, virtualbox.
