| Di seguito sono consultabili le note di rilascio - in gergo "release notes" - relative al file VirtualBox 3.0.0 beta 1, nel caso in cui gli sviluppatori abbiano reso disponibile tale documentazione in occasione della pubblicazione del software. Tuttavia, se hai bisogno di maggiori informazioni su VirtualBox 3.0.0 beta 1, o se le note di rilascio non sono (ancora) disponibili, è comunque possibile procedere con la lettura della descrizione del file. |
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)
- 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 fixed and/or added:
- Virtual mouse device: eliminated micro-movements of the virtual mouse which
were confusing some applications (bug #3782)
- Solaris hosts: allow suspend/resume on the host when a VM is running (bug
#3826)
- Solaris hosts: tighten the restriction for contiguous physical memory under certain
conditions
- VMM: fixed 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 (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)
- GUI: added mini toolbar for fullscreen and seamless mode (Thanks to Huihong
Luo)
153
- 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 (bug #4157)
- VRDP: support Windows 7 RDP client
- Networking: fixed another problem with TX checksum offloading with Linux
kernels up to version 2.6.18
- VHD: properly write empty sectors when cloning of VHD images (bug #4080)
- VHD: fixed crash when discarding snapshots of a VHD image
- VBoxManage: fixed incorrect partition table processing when creating VMDK
files giving raw partition access (bug #3510)
- OVF: several OVF 1.0 compatibility fixes
- 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: fixed incorrect file timestamps, when using Windows guest on a
Linux host (bug #3404)
- 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 configure socket and internal parameters
- Registration dialog uses Sun Online accounts now.
