Specifically, Innotek developed the additions code in both Microsoft Virtual PC and Microsoft Virtual Server, which enables various host guest OS interactions like shared clipboards or dynamic viewport resizing.

Oracle defines personal use as the installation of the software on a single host computer for non commercial purposes. Prior to version 4, there were two different packages of the Virtual. Box software. The full package was offered free under the PUEL, with licenses for other commercial deployment purchasable from Oracle. A second package called the Virtual.

Sybase Open Watcom Public License is approved as Open Source by the Open Source Initiative2. Free Software Foundation or under the Debian Free Software Guidelines. Although Virtual. Box has experimental support for Mac OS X guests, the end user license agreement of Mac OS X does not permit the operating system to run on non Apple hardware, and this is enforced within the operating system by calls to the Apple System Management Controller SMC in all Apple machines, which verifies the authenticity of the hardware. Emulated environmenteditUsers of Virtual. Box can load multiple guest OSs under a single host operating system host OS. Each guest can be started, paused and stopped independently within its own virtual machine VM. 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. The host OS and guest OSs and applications can communicate with each other through a number of mechanisms including a common clipboard and a virtualized network facility. Guest VMs can also directly communicate with each other if configured to do so. Software based virtualizationeditIn the absence of hardware assisted virtualization, Virtual. Box adopts a standard software based virtualization approach. This mode supports 3. OSs which run in rings 0 and 3 of the Intel ring architecture. The system reconfigures the guest OS code, which would normally run in ring 0, to execute in ring 1 on the host hardware. Because this code contains many privileged instructions which cannot run natively in ring 1, Virtual. Box 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. This replaces the instruction with a jump to a VM safe equivalent compiled code fragment in hypervisor memory. The guest user mode code, running in ring 3, generally runs directly on the host hardware in ring 3. In both cases, Virtual. Box uses CSAM and PATM to inspect and patch the offending instructions whenever a fault occurs. Virtual. Box also contains a dynamic recompiler, based on QEMU to recompile any real mode or protected mode code entirely e. BIOS code, a DOS guest, or any operating system startup. Using these techniques, Virtual. Box can achieve a performance comparable to that of VMware. Hardware assisted virtualizationeditVirtual. Box supports both Intels VT x and AMDs AMD V hardware virtualization. Making use of these facilities, Virtual. Box 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 VMX non root mode rather than in ring 1. Virtual. Box supports some guests including 6. SMP guests and certain proprietary OSs only on hosts with hardware assisted virtualization. Device virtualizationedit The system emulates hard disks in one of three disk image formats VDI This format is the Virtual. Box specific Virtual. Box Disk Image and stores data in files bearing a.

Box virtual machine can, therefore, use disks previously created in VMware or Microsoft Virtual PC, as well as its own native format. Virtual. Box can also connect to i.
