برنامج VirtualBox 3.0.2 VirtualBox_wm

VirtualBox is a powerful x86 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL). See "About VirtualBox" for an introduction.

Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and OpenBSD.

VirtualBox is being actively developed with frequent releases and has an ever growing list of features, supported guest operating systems and platforms it runs on. VirtualBox is a community effort backed by a dedicated company: everyone is encouraged to contribute while Sun ensures the product always meets professional quality criteria.

Some of the features of VirtualBox are:
• Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
• Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
• Guest Additions for Windows and Linux. VirtualBox has special software that can be installed inside Windows and Linux virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window).
• Shared

folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.

Version 3.0 will be a major update. The following major new features were added:
• Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only)
• Windows guests: ability to use Direct3D 8/9 applications / games (experimental)
• Support for OpenGL 2.0 for Windows, Linux and Solaris guests

In addition, the following items were ?xed and/or added:
• Virtual mouse device: eliminated micro-movements of the virtual mouse which were confusing some applications
• Solaris hosts: allow suspend/resume on the host when a VM is running
• Solaris hosts: tighten the restriction for contiguous physical memory under certain conditions
• VMM: ?xed occassional guru meditation when loading a saved state (VT-x only)
• VMM: eliminated IO-APIC overhead with 32 bits guests (VT-x only, some Intel CPUs don’t support this feature
• VMM: ?xed 64 bits CentOS guest hangs during early boot
• VMM: performance improvements for certain PAE guests
• GUI: added mini toolbar for fullscreen and seamless mode (Thanks to Huihong Luo)
• GUI: redesigned settings dialogs
• GUI: allow to create/remove one host-only network adapters
• GUI: display estimated time for long running operations (e.g. OVF import/export)
• GUI: Fixed rare hangs when open the OVF import/export wizards
• VRDP: support Windows 7 RDP client
• Networking: ?xed another problem with TX checksum of?oading with Linux kernels up to version 2.6.18
• VHD: properly write empty sectors when cloning of VHD images
• VHD: ?xed crash when discarding snapshots of a VHD image
• VBoxManage: ?xed incorrect partition table processing when creating VMDK ?les giving raw partition access
• OVF: several OVF 1.0 compatibility ?xes
• Shared

Folders: sometimes a ?le was created using the wrong permissions (2.2.0 regression;
• Shared

Folders: allow to change ?le attributes from Linux guests and use the correct ?le mode when creating ?les
• Shared

Folders: ?xed incorrect ?le timestamps, when using Windows guest on a Linux host
• Linux guests: new daemon vboxadd-service to handle time syncronization and guest property lookup
• Linux guests: implemented guest properties (OS info, logged in users, basic network information)
• Windows host installer: VirtualBox Python API can now be installed automatically (requires Python and Win32 Extensions installed)
• USB: Support for high-speed isochronous endpoints has been added. In addition, read-ahead buffering is performed for input endpoints (currently Linux hosts only). This should allow additional devices to work, notably webcams
• NAT: allow to con?gure socket and internal parameters
• Registration dialog uses Sun Online accounts now
