Oracle VirtualBox (formerly Sun VirtualBox, innotek VirtualBox and Sun xVM VirtualBox) is a free and cross-platform virtualization application that provides a family of powerful x86 virtualization tools designed for desktop, server and embedded use. VirtualBox can be used on Linux, Solaris, Mac OS X and Microsoft Windows platforms to run virtual machines of any of the aforementioned operating systems, as well as any BSD distribution, IMB OS/2 flavors, DOS, Netware, L4, QNX, and JRockitVE.

Oracle VirtualBox is portable, requires no hardware virtualization, includes guest additions and great hardware support. It also features USB device support, full ACPI support, multiscreen resolutions, and built-in iSCSI support. Support for PXE network boot, multigeneration branched snapshots, remote machine display, extensible RDP authentication, and USB over RDP (Remote Desktop Protocol) is also integrated in Oracle VirtualBox.

At the moment, the program is capable of running only AMD64/Intel64 and x86 architectures. By default, when creating a new virtual machine, you will be able to select the operating system that you plan on virtualizing. Ever since Oracle acquired the Sun Microsystems company, VirtualBox is actively developed by a team of professional engineers who implement new features and functionality with every release.

• VMM: fixed a Guru Meditation when rebooting certain guests (for example Solaris doing fast reboot) by fixing the implementation for INIT IPI
• VMM: added some information for diagnosing rare VERR_VMX_INVALID_VMXON_PTR Guru Meditations (VT-x only)
• GUI: HID LEDs sync: prevent synchronization if VM window has no focus (Windows and Mac OS X hosts only)
• GUI: fixed drag and drop moving the cursor between guest screens on certain hosts
• 3D: fixed a crash on restoring the VM state on X11 hosts
• 3D: fixed a crash on Linux guest shutdown
• VRDP: fixed incompatibility with rdesktop 1.8.3
• VRDP: fixed listening for IPv6 on some systems
• Storage: don’t crash if creating an asynchronous I/O context fails (e.g. when starting many VMs) and show a proper error message
• Floppy: several fixes
• Audio: improved the behavior of the volume control for the HD audio device emulation
• USB: increase the number of supported drivers from 3 to 5 (Windows hosts only)
• PS/2 keyboard: synchronize the LED state on VM restore (Windows and Mac OS X hosts only)
• NAT Network: when running multiple NAT networks with multiple VMs, only stop the respective services when stopping VMs
• NAT: don’t kill UDP bindings on ICMP errors
• NAT: bandwidth limit now works properly with NAT
• BIOS: fixed the returned size value of the VBE 2.0 PMI function 0Ah
• Guest Control: fixed parameter quoting in Windows guests
• Webcam passthrough improvements for Linux (V4L2) hosts to support more webcam models
• API: don’t fail starting a VM with VBOX_E_INVALID_OBJECT_STATE under certain conditions
• API: be more verbose on VBOX_E_INVALID_OBJECT_STATE if a medium is attached to a running VM
• API: fixed a bug which could result in losing certain screen resize events with multi-monitor guests
• rdesktop-vrdp: fixed path to the keymaps
• rdesktop-vrdp: switch to version 1.8.3
• Windows hosts: more hardening fixes
• Linux hosts: another fix for activated SMAP on Linux 3.19 and newer (Broadwell and later)
• Linux hosts: Linux 4.1 compile fix
• Solaris hosts: fixed using of VNIC templates with Crossbow based bridged networking to be compatible with vanity interface names
• Mac OS X hosts: fixed crash during VM termination under rare circumstances
• Windows Additions/WDDM: improved video memory utilization and allow more/bigger guest screens with large resolutions (including HiDPI)
• X11 Additions: prevent flickering when updating mouse cursor
• Solaris Additions: fixed incorrect usage of ‘prtconf’ while installing Guest Additions (Solaris 10 only)
