| | 4 | This version is a major update. The following major new features were added: |
| | 5 | * Support for hardware virtualization (VT-x and AMD-V) on Mac OS X hosts |
| | 6 | * Support for 64-bit guests on 32-bit host operating systems (experimental; see user manual, chapter 1.6, 64-bit guests, page 16) |
| | 7 | * 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)) |
| | 8 | * Experimental 3D acceleration via OpenGL (see user manual, chapter 4.8, Hardware 3D acceleration (OpenGL), page 66) |
| | 9 | * Experimental !LsiLogic and !BusLogic SCSI controllers (see user manual, chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, page 70) |
| | 10 | * Full VMDK/VHD support including snapshots (see user manual, chapter 5.2, Disk image files (VDI, VMDK, VHD), page 72) |
| | 11 | * New NAT engine with significantly better performance, reliability and ICMP echo (ping) support (bugs #1046, #2438, #2223, #1247) |
| | 12 | * New Host Interface Networking implementations for Windows and Linux hosts with easier setup (replaces TUN/TAP on Linux and manual bridging on Windows) |
| | 13 | In addition, the following items were fixed and/or added: |
| | 14 | * VMM: significant performance improvements for VT-x (real mode execution) |
| | 15 | * VMM: support for hardware breakpoints (VT-x and AMD-V only; bug #477) |
| | 16 | * VMM: VGA performance improvements for VT-x and AMD-V |
| | 17 | * VMM: Solaris and !OpenSolaris guest performance improvements for AMD-V (Barcelona family CPUs only) |
| | 18 | * VMM: fixed guru meditation while running the Dr. Web virus scanner (software virtualization only; bug #1439) |
| | 19 | * 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) |
| | 20 | * VMM: fixed guest hangs when restoring VT-x or AMD-V saved states/snapshots |
| | 21 | * VMM: fixed guru meditation when executing a one byte debug instruction (VT-x only; bug #2617) |
| | 22 | * VMM: fixed guru meditation for PAE guests on non-PAE hosts (VT-x) |
| | 23 | * VMM: disallow mixing of software and hardware virtualization execution in general (bug #2404) |
| | 24 | * VMM: fixed black screen when booting OS/2 1.x (AMD-V only) |
| | 25 | * GUI: pause running VMs when the host machine goes into suspend mode (Windows & Mac OS X hosts) |
| | 26 | * GUI: resume previously paused VMs when the host machine resumes after suspend (Windows & Mac OS X hosts) |
| | 27 | * GUI: save the state of running or paused VMs when the host machine’s battery reaches critical level (Windows hosts) |
| | 28 | * GUI: properly restore the position of the selector window when running on the compiz window manager |
| | 29 | * GUI: properly restore the VM in seamless mode (2.0 regression) |
| | 30 | * GUI: warn user about non optimal memory settings |
| | 31 | * GUI: structure operating system list according to family and version for improved usability |
| | 32 | * GUI: predefined settings for QNX guests |
| | 33 | * IDE: improved ATAPI passthrough support |
| | 34 | * Networking: added support for up to 8 Ethernet adapters per VM |
| | 35 | * Networking: fixed issue where a VM could lose connectivity after a reboot |
| | 36 | * iSCSI: allow snapshot/diff creation using local VDI file |
| | 37 | * iSCSI: improved interoperability with iSCSI targets |
| | 38 | * Graphics: fixed handling of a guest video memory which is not a power of two (bug #2724) |
| | 39 | * VBoxManage: fixed bug which prevented setting up the serial port for direct device access. |
| | 40 | * VBoxManage: added support for VMDK and VHD image creation |
| | 41 | * VBoxManage: added support for image conversion (VDI/VMDK/VHD/RAW) |
| | 42 | * Solaris hosts: added IPv6 support between host and guest when using host interface networking |
| | 43 | * Mac OS X hosts: added ACPI host power status reporting |
| | 44 | * API: redesigned storage model with better generalization |
| | 45 | * API: allow attaching a hard disk to more than one VM at a time |
| | 46 | * API: added methods to return network configuration information of the host system |
| | 47 | * Shared Folders: performance and stability fixes for Windows guests (Microsoft Office Applications) |
