| VirtualBox 3.2.6.63112 - FinalVirtualBox 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). 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. A number of extra features are available with the full VirtualBox release only (see the "Editions" page for details):• Virtual USB Controllers. VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device specific drivers on the host. • Remote Desktop Protocol. Unlike any other virtualization software, VirtualBox fully supports the standard Remote Desktop Protocol (RDP). A virtual machine can act as an RDP server, allowing you to "run" the virtual machine remotely on some thin client that merely displays the RDP data. • USB over RDP. With this unique feature, a virtual machine that acts as an RDP server can still access arbitrary USB devices that are connected on the RDP client. This way, a powerful server machine can virtualize a lot of thin clients that merely need to display RDP data and have USB devices plugged in.
Changes in VirtualBox 3.2.6 (released 2010-06-25): * VMM: fixed host crash when running 64-bit guests on 32-bit hosts with certain Intel CPUs (VT-x only; bug #6166) * VMM: allow 64-bit SMP guests on 32-bit hosts (VT-x and AMD-V only; does not apply to Mac OS X, which already supports it) * VMM: fixed Guru mediation if guests with more than 2GB are booted with VT-x/AMD-V disabled (bug #5740) * VMM: fixed TR limit trashing (VT-x and 64-bit host only; bug #7052) * Page Fusion: several bug fixes for SMP guests (including bug #6964) * Teleportation: several fixes and improvements * Mac OS X server guests: compatibility fix * EFI: fixed memory detection for guests with 2GB or more RAM assigned * GUI: added a workaround for a Linux kernel bug which affecting asynchronous I/O on ext4 / xfs file systems (Linux hosts only) * GUI: added setting for multiple VRDP connections; useful if multiple screens are enabled * GUI: another fix for the keyboard capturing bug under metacity (bug #6727) * GUI: fixed quit dialog when used in seamless or fullscreen mode (Mac OS X hosts only; bug #6938) * GUI: handle the extra key on the Brazilian keyboard on X11 hosts again (bug #7022). * 2D Video acceleration: fixed crashes when leaving the fullscreen mode (bug #6768) * VBoxManage: fixed storageattach error handling (bug #6927) * VBoxManage: fixed dhcpserver add (3.2.0 regression; bug #7031) * Storage: fixed hang with images located on filesystems which don't support async I/O (bug #6905) * Storage: fixed raw disks on Windows hosts (3.2.0 regression; bug #6987) * LsiLogic: fixed hang with older Linux guests * BusLogic: fixed hang during I/O * SATA: set initial number of ports to 1 as some guests can't handle 30 ports (e.g. CentOS 4 and FreeBSD; bug #6984) * SATA: performance improvement * SCSI: fixed error when using the full format option during Windows installation (bug #5101) * iSCSI: fixed authentication (bug #4031) * Host-only/bridged networking: fixed excessive host kernel warnings under certain circumstances (Linux hosts only; 3.2.0 regression; bug #6872) * NAT: fixed potential memory leaks * NAT: increased the size of the memory pool for 16K Jumbo frames (performance tweak) * NAT: allow to link/unlink the network cable even if the VM is currently paused * E1000: disconnect cable was not properly handled if the NIC was not yet initialized by the guest * OVF: export performance optimization * OVF: upgraded OS type definitions to CIM 2.25.0 so that Windows 7 and other OSes are now tagged correctly on export * Settings: the setting for disabling the host I/O cache was sometimes not properly saved * Settings: save machine state into XML correctly even when snapshot folder has been changed to a non-default location (bug #5656) * USB: allow the guest to disable an EHCI port * USB: find a valid language ID before querying strings (bug #7034) * POSIX hosts: fixed several memory leaks (3.2.0 regression) * Solaris hosts: fixed VDI access problem under certain circumstances (IDE/SATA; 3.2.0 regression) * Solaris hosts: fixed VM fails to start on 32-bit hosts (3.2.0 regression; bug #6899) * Windows hosts (32-bit): increase guest RAM limit if the host kernel allows for more virtual address space * Linux Additions: re-read a directory after a file was removed (bug #5251) * Linux Additions: install the DRI driver in the right location on ArchLinux guests (bug #6937) * X11 Additions: fixed spurious mouse movement events (bug #4260) * Solaris Additions: fixed guest control execution * Windows Additions: automatic logon on Windows Vista/Windows 7 is now able to handle renamed and principal user accounts; added various bugfixes * Windows Additions: improved command line parsing of the installer * Windows Additions: fixed driver verifier bugcheck in VBoxMouse (bug #6453) * 3D support: fixed OpenGL support for 32bit apps under 64bit Windows guests Homepage - Trang chủSize: 75.3 MB Download - Tải về phiên bản dành cho Windows Download - Tải về phiên bản dành cho các hệ máy khác |
