VirtualBox is an x86 virtualization software package, originally created by German software company Innotek, now developed by Sun Microsystems as part of its Sun xVM virtualization platform. VirtualBox is installed on an existing host operating system; within this application, additional operating systems, each known as a Guest OS, can be loaded and run, each with its own virtual environment. VirtualBox supported host operating systems include Linux, Mac OS X, OS/2 Warp, Windows XP, Windows Vista, Windows 7 and Solaris; there is also an experimental port to FreeBSD. VirtualBox supported guest operating systems include a small number of versions of NetBSD and various versions of DragonFlyBSD, FreeBSD, Linux, OpenBSD, OS/2 Warp, Windows, Solaris, Haiku, Syllable, ReactOS and SkyOS. VirtualBox latest version also supports Windows 7.

VirtualBox Features:
- 64-bit guests (64-bit hosts with CPU virtualization extensions or experimentally on 64-bit capable 32-bit host operating systems)
- NCQ support for SATA raw disks and partitions
- Snapshots
- Seamless mode
- Clipboard
- Shared folders
- Special drivers and utilities to facilitate switching between systems
- Experimental OpenGL drivers for win32 and Linux to render on Host hardware
- Command line interaction (in addition to the GUI)
- Public API (Java, Python, SOAP, XPCOM) to control VM configuration and execution [17]
- Remote display (useful for headless host machines)
- Nested paging for AMD-V and Intel Core i7
- Raw hard disk access - allows physical hard disk partitions on the host system to appear in the guest system
- VMware Virtual Machine Disk Format (VMDK) support - allows VirtualBox to exchange disk images with VMware
- Microsoft VHD support
- 3D virtualization (Limited support for OpenGL was added to v2.1, more support was added to v2.2, penGL 2.0 and Direct3D support was added in VirtualBox 3.0)
- SMP support (up to 32 virtual CPUs), since version 3.0
Only available in the full (closed source) version:
- Remote Desktop Protocol (RDP) control of VM
- USB support, with remote devices over RDP
- iSCSI support
- Open Virtualization Format (OVF) support (import/export)
- VMM: reduced IO-APIC overhead for 32 bits Windows NT/2000/XP/2003 guests; requires 64 bits support (VT-x only; bug #4392)
- VMM: fixed double timer interrupt delivery on old Linux kernels using IO-APIC (caused guest time to run at double speed; bug #3135)
- VMM: reinitialize VT-x and AMD-V after host suspend or hibernate; some BIOSes forget this (Windows hosts only; bug #5421)
- VMM: fix loading of saved state when RAM preallocation is enabled
- BIOS: ignore unknown shutdown codes instead of causing a guru meditation (bug #5389)
- GUI: never start a VM on a single click into the selector window (bug #2676)
Serial: reduce the probability of lost bytes if the host end is connected to a raw file
- VMDK: fix handling of split image variants and fix a 3.0.10 regression (bug #5355)
- VRDP: fixed occasional VRDP server crash
- Network: even if the virtual network cable was disconnected, some guests were able to send / receive packets (E1000; bug #5366)
- Network: even if the virtual network cable was disconnected, the PCNet card received some spurious packets which might confuse the guest (bug #4496)
- Shared folders: fixed changing case of file names (bug #2520)
- Windows Additions: fix crash in seamless mode (contributed by Huihong Luo)
- Linux Additions: fix writing to files opened in O_APPEND mode (bug #3805)
- Solaris Additions: fix regression in guest additions driver which among other things caused lost guest property updates and periodic error messages being written to the system log
