V3.0 的改变
VirtualBox 3.0.0 (released 2009-06-30)
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 of the user manual)
- Windows guests: ability to use Direct3D 8/9 applications / games (experimental; see chapter 4.8 of the user manual)
- 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 to 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 #1187)
- 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 beinstalled automatically (requires Python and Win32 Extensionsinstalled)
- USB: Support for high-speed isochronous endpoints has beenadded. In addition, read-ahead buffering is performed for inputendpoints (currently Linux hosts only). This should allow additionaldevices to work, notably webcams (bug #242).
- USB: fixed error handling for some USB dongles
- Web service: fixed inability to handle NULL pointers for objectarguments, which are valid values for a lot of APIs, in both the rawand 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
已经换成30 ,用系统卸载来卸载,不用重启,重装仍然按原路径,原来创建的虚拟电脑一样用。
打开虚拟系统就提示发现新硬件, 可能是映射主机的CPU ,成了intel ,不再像以前只是AMD 的了。上网正常,其它还没什么感觉,要多用虚拟系统才会有发现。 |
