Please do NOT use this VirtualBox Beta release on production machines. A VirtualBox Beta release should be considered a bleeding-edge release meant for early evaluation and testing purposes.

You can download the binaries here.

Please do NOT open bug reports at http://www.virtualbox.org/wiki/Bugtracker but use our VirtualBox Beta Feedback forum to report any problems with the Beta. Please concentrate on reporting regressions since VirtualBox 4.0.10 / VirtualBox 4.1 Beta 2.

The following items were fixed / added since the VirtualBox 4.1 Beta 2:

• GUI: reworked media type change dialog
• GUI: when cloning or importing a VM, let the user decide if he wants to change the MAC addresses of the network adapters
• GUI: allow to change generic networking properties during runtime
• GUI: allow to configure the port count of SATA controllers (required for SATA hotplugging)
• Cloning: allow linked cloning (see VBoxManage clonevm, GUI support will follow)
• Cloning: rename the disks in the clone
• PCI passthrough: allow to start the VM if the ICH9 chipset is enabled and the extension pack is not available (Beta 2 regression)
• 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 guestcontrol fixes
• Storage: fixed access to CD/DVD images beyond 4GB when using the SATA controller (bug #8592)
• Networking: fixed the problem with segmentation offloading when several VMs are transmitting in parallel
• WDDM fixes
• Mac OS X hosts: fix for non-VT-x mode on Lion
• Solaris hosts: fixed for recent S11 versions
