VirtualBox 4.1正式版发布

On 2011年07月20日, in soft, by netoearth

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

  • Support for cloning of VMs (bug #5853, see the manual for more information): full clones can be created through the GUI and VBoxManage, linked clones only through VBoxManage
  • GUI: enhanced wizard for creating new virtual disks
  • GUI: new wizard for copying virtual disks
  • GUI: keep the aspect ratio in scale mode (Windows and OSX hosts only; bug #7822)
  • VMM: raised the memory limit for 64-bit hosts to 1TB
  • Experimental support for PCI passthrough for Linux hosts, see the manual for more information
  • Windows guests: Experimental WDDM graphics driver, supporting Windows Aero (bug #4607) and providing Direct3D support using a cleaner approach (no need to install the guest drivers in Safe Mode anymore)
  • Guest Additions: status of modules and features can now be queried separately by the frontends
  • Networking: new network attachment mode “Generic Driver”, which offers an open plugin architecture for arbitrary and separately distributable virtual network implementations
  • Host-only Networking: fixed host crash in kernels prior to 2.6.29
  • New Networking Mode UDP Tunnel: allows to interconnect VMs running on different hosts easily and transparently, see the manual for more information
  • Experimental support for SATA hard disk hotplugging available with VBoxManage
  • Solaris hosts: New Crossbow based bridged networking driver for Solaris 11 build 159 and above

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

  • VMM: more SMP timer fixes
  • VMM: fixed sporadic recompiler crashes with SMP guests
  • VMM: many small fixes
  • GUI: when reverting to a snapshot, ask for taking a snapshot of the current state
  • GUI: added a View menu
  • GUI: added a setting for the promiscuous mode policy for internal networks, bridged networks and host-only networks
  • GUI: added slider for setting the CPU execution cap allowing to limit the amount of CPU time spent for the execution of the guest, see the manual for more information.
  • GUI: the VM description is editable during the runtime of a VM (bug #1551)
  • GUI: added proxy settings (bug #2870)
  • GUI: made the number of SATA ports configurable
  • GUI: decrease time before showing the VM configuration dialog
  • VBoxManage: more convenient configuration of storage controller attachments by automatically determining the port or device parameter when a storage controller has only one port or device per port
  • VBoxManage: changed syntax of the guestcontrol command group, fixed various bugs, removed obsolete options
  • VBoxBalloonCtrl: new service for automatic dynamic adjustment of the balloon size for running VMs
  • Settings: machine names and snapshot names are not allowed to be a valid UUID
  • Settings: provide better diagnostics if a single medium is used twice in a VM configuration
  • Settings: provide better diagnostics for errors in medium create/merge/clone operations, and fix memory leaks in error cases
  • Storage: ATA/SATA drives can be marked as non-rotational, i.e. the guest OS will detect them as a SSD if supported, which can improve performance
  • Storage: virtual CD/DVD images will be detached if the guest ejects the medium, unless the drive is marked to handle ejects only on a temporary basis
  • Storage: the medium UUID can be changed again when attaching a medium for the first time, which allows using images which are exact duplicates including the UUID
  • Storage: fixed possible data corruption under certain circumstances with VHD and Parallels images (bug fixed in svn (closed)” href=”http://www.virtualbox.org/ticket/8592″>#8592)
  • Floppy: several bugs have been fixed
  • Floppy: make it possible to unmount a host floppy disk (bug #8739)
  • USB: many fixes for the Windows USB host driver
  • NAT: reduced memory footprint
  • Networking: fixed the problem with segmentation offloading when several VMs are transmitting in parallel
  • Networking: workaround for a bug in wireshark when operating directly on a capture file created by VirtualBox
  • Serial: announce the serial devices in the ACPI tables to make Windows guests find the virtual hardware (bug Fixed in SVN (closed)” href=”http://www.virtualbox.org/ticket/8916″>#8916)
  • Webservice: fixed timeout handling with HTTP 1.1 keepalive, and be more robust when connections fail
  • VBoxSVC: fixed regression when several clients trigger autostart simultaneously
  • Main: fixed incorrect handling of the medium location for media which are not file based (e.g. iSCSI), which resulted in confusing location values in many places
  • JAX-WS client bindings: fixed resource leak
  • Sources: fixed USB 2.0 support using extension packs for non-official builds
  • Mac OS X hosts: fixed non-VT-x mode on Lion hosts
  • Windows hosts: fixed copy’n’paste in the GUI and for the VM window (bug #4491)
  • Windows hosts (64-bit only): enabled removing of all mediums when removing a VM
  • Windows hosts (64-bit only): enabled live snapshot deletion
  • Windows hosts: use native controls in the installer (bug Fixed in SVN (closed)” href=”http://www.virtualbox.org/ticket/8014″>#8014)
