Changelog:

This version is a major update. The following major new features were added:

    * Support for hardware virtualization (VT-x and AMD-V) on Mac OS X hosts
    * Support for 64-bit guests on 32-bit host operating systems (experimental; see user manual, chapter 1.6, 64-bit guests, page 16)
    * Added support for Intel Nehalem virtualization enhancements (EPT and VPID; see user manual, chapter 1.2, Software vs. hardware virtualization (VT-x and AMD-V), page 10))
    * Experimental 3D acceleration via OpenGL (see user manual, chapter 4.8, Hardware 3D acceleration (OpenGL), page 66)
    * Experimental LsiLogic and BusLogic SCSI controllers (see user manual, chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, page 70)
    * Full VMDK/VHD support including snapshots (see user manual, chapter 5.2, Disk image files (VDI, VMDK, VHD), page 72)
    * New NAT engine with significantly better performance, reliability and ICMP echo (ping) support (bugs #1046, #2438, #2223, #1247)
    * New Host Interface Networking implementations for Windows and Linux hosts with easier setup (replaces TUN/TAP on Linux and manual bridging on Windows)

In addition, the following items were fixed and/or added:

    * VMM: significant performance improvements for VT-x (real mode execution)
    * VMM: support for hardware breakpoints (VT-x and AMD-V only; bug #477)
    * VMM: VGA performance improvements for VT-x and AMD-V
    * VMM: Solaris and OpenSolaris guest performance improvements for AMD-V (Barcelona family CPUs only)
    * VMM: fixed guru meditation while running the Dr. Web virus scanner (software virtualization only; bug #1439)
    * VMM: deactivate VT-x and AMD-V when the host machine goes into suspend mode; reactivate when the host machine resumes (Windows, Mac OS X & Linux hosts; bug #1660)
    * VMM: fixed guest hangs when restoring VT-x or AMD-V saved states/snapshots
    * VMM: fixed guru meditation when executing a one byte debug instruction (VT-x only; bug #2617)
    * VMM: fixed guru meditation for PAE guests on non-PAE hosts (VT-x)
    * VMM: disallow mixing of software and hardware virtualization execution in general (bug #2404)
    * VMM: fixed black screen when booting OS/2 1.x (AMD-V only)
    * GUI: pause running VMs when the host machine goes into suspend mode (Windows & Mac OS X hosts)
    * GUI: resume previously paused VMs when the host machine resumes after suspend (Windows & Mac OS X hosts)
    * GUI: save the state of running or paused VMs when the host machine’s battery reaches critical level (Windows hosts)
    * GUI: properly restore the position of the selector window when running on the compiz window manager
    * GUI: properly restore the VM in seamless mode (2.0 regression)
    * GUI: warn user about non optimal memory settings
    * GUI: structure operating system list according to family and version for improved usability
    * GUI: predefined settings for QNX guests
    * IDE: improved ATAPI passthrough support
    * Networking: added support for up to 8 Ethernet adapters per VM
    * Networking: fixed issue where a VM could lose connectivity after a reboot
    * iSCSI: allow snapshot/diff creation using local VDI file
    * iSCSI: improved interoperability with iSCSI targets
    * Graphics: fixed handling of a guest video memory which is not a power of two (bug #2724)
    * VBoxManage: fixed bug which prevented setting up the serial port for direct device access.
    * VBoxManage: added support for VMDK and VHD image creation
    * VBoxManage: added support for image conversion (VDI/VMDK/VHD/RAW)
    * Solaris hosts: added IPv6 support between host and guest when using host interface networking
    * Mac OS X hosts: added ACPI host power status reporting
    * API: redesigned storage model with better generalization
    * API: allow attaching a hard disk to more than one VM at a time
    * API: added methods to return network configuration information of the host system
    * Shared Folders: performance and stability fixes for Windows guests (Microsoft Office Applications)
