The second beta release of VirtualBox 4.1 is now available for download and testing. You can find binaries for your host platform at http://download.virtualbox.org/virtualbox/4.1.0_BETA2. This release contains several new features which may not be quite complete. Please do not use this on any production systems - it is only for early evaluation and testing.
VirtualBox 4.1 will be a new major release and includes the following new features.
Support for cloning virtual machines
Enhanced wizard for creating new virtual disks
A new wizard for copying virtual disks
Increased the guest memory limit for 64-bit hosts to 1TB
Experimental WDDM graphics driver for Windows guests
Modules and features in the guest additions now are represented as facilities to have a common interface for frontends.
A new networking mode (UDP tunnel) which will allow easy and transparent communication between guests running on different hosts
VMM: fixed a Beta 1 regression which prevented certain guests from booting
VMM: better out-of-memory error reporting under certain circumstances
GUI: display CPU cap in the VM details page
Storage: introduced non-rotational flag for hard disks for optimizing the performance with modern guests (e.g. Windows 7 will not automatically defrag the disk)
Floppy: make unmounting a host floppy disk work
Solaris hosts: Host-only/Bridged networking fixes
Solaris guests: fixed automounting of shared folders
Linux installer: fixed compilation of the vboxpci module if DKMS is not installed
Windows Installer: fixed automated VBox Python API installation.
Experimental support for PCI passthrough (Linux hosts only)
Please report any problems with the beta release at the VirtualBox Beta Forum. The development team is particularly interested in problems or regressions since the last release (4.0.10).
