VirtualBox v3.0.0 - 模擬器

http://www.virtualbox.org/

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

‧ Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only; see chapter
3.7.2.2, “Processor” tab, page 48)
‧ Windows guests: ability to use Direct3D 8/9 applications / games
(experimental; see chapter 4.8, Hardware 3D acceleration (OpenGL and DirectX
8/9), page 71)
‧ Support for OpenGL 2.0 for Windows, Linux and Solaris guests


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

‧ Solaris hosts: allow suspend/resume on the host when a VM is running (bug
#3826)
‧ Solaris hosts: loosen the restriction for contiguous physical memory under
certain conditions
‧ Mac OS X hosts: fixed guest PAE
‧ Linux hosts: kernel module compile fixes for 2.6.31 (bug #4264)
‧ VMM: fixed occasional 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 (most do); bug #638)
‧ VMM: fixed 64 bits CentOS guest hangs during early boot (AMD-V only; bug
#3927)
‧ VMM: performance improvements for certain PAE guests (e.g. Linux 2.6.29+
kernels)
‧ VMM: some Windows guests detected a completely wrong CPU frequency (bug
#2227)
‧ VMM: fixed hanging and unkillable VM processes (bug #4040)
‧ VMM: fixed random infrequent guest crashes due XMM state corruption (Win64
hosts only)
‧ VMM: performance improvements for network I/O (VT-x/AMD-V only)
‧ GUI: added mini toolbar for fullscreen and seamless mode (Thanks to
Huihong Luo)
‧ GUI: redesigned settings dialogs
‧ GUI: allow to create/remove more than one host-only network adapters (non
Windows hosts)
‧ GUI: display estimated time for long running operations (e.g. OVF
import/export)
‧ GUI: fixed rare hangs when open the OVF import/export wizards (bug #4157)
‧ 3D support: fixed VM crashes for client applications using incorrect
OpenGL states
‧ 3D support: fixed memory corruption when querying for supported texture
compression formats
‧ 3D support: fixed incorrect rendering of glDrawRangeElements
‧ 3D support: fixed memory leak when using VBOs
‧ 3D support: fixed glew library detection
‧ 3D support: fixed random textures corruption
‧ VRDP: support Windows 7 RDP client
‧ Networking: fixed another problem with TX checksum offloading with Linux
kernels up to version 2.6.18
‧ NAT: fixed “open ports on virtual router 10.0.2.2 - 513, 514” (forum)
‧ NAT: allow to configure socket and internal parameters
‧ NAT: allow to bind sockets to specific interface
‧ PXE boot: significant performance increase (VT-x/AMD-V only)
‧ VHD: properly write empty sectors when cloning of VHD images (bug #4080)
‧ VHD: fixed crash when discarding snapshots of a VHD image
‧ VHD: fixed access beyond the block bitmap which could lead to arbitrary
crashes
‧ VBoxManage: fixed incorrect partition table processing when creating VMDK
files giving raw partition access (bug #3510)
‧ VBoxManage: support cloning to existing image file
‧ OVF: several OVF 1.0 compatibility fixes
‧ OVF: fixed exporting of disk images when multiple virtual machines are
exported at once
‧ Virtual mouse device: eliminated micro-movements of the virtual mouse which
were confusing some applications (bug #3782)
‧ Shared Folders: sometimes a file was created using the wrong permissions
(2.2.0 regression; bug #3785)
‧ Shared Folders: allow to change file attributes from Linux guests and use
the correct file mode when creating files
‧ Shared Folders: some content was incorrectly written under certain
conditions (bug #11187)
‧ Shared Folders: fixed incorrect file timestamps, when using Windows guest
on a Linux host (bug #3404)
‧ X11 clipboard: fix duplicate end of lines (bug #4270)
‧ X11 guests: a number of shared clipboard fixes
‧ Linux guests: Guest Additions support for SUSE Linux Enterprise Desktop 11
‧ Linux guests: new daemon vboxadd-service to handle time synchronization
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 (bug #242).
‧ USB: fixed error handling for some USB dongles
‧ Web service: fixed inability to handle NULL pointers for object arguments,
which are valid values for a lot of APIs, in both the raw and the object-
oriented web service.
‧ Web service: object-oriented bindings for JAX-WS did not exhibit interface
inheritance correctly, fixed
‧ Web service: added support for IDisplay and IGuest interfaces, which were
previously unavailable
‧ Registration dialog uses Sun Online accounts now
