Sun xVM VirtualBox v. 3.1.0 has been released

Sun xVM VirtualBox v. 3.1.0 has been released. This is a major update which introduces some brand-new great features such as (change log excerpt):

• Teleportation (aka live migration); migrate a live VM session from one host to another (see the manual for more information)
• VM states can now be restored from arbitrary snapshots instead of only the last one, and new snapshots can be taken from other snapshots as well ("branched snapshots"; see the manual for more information)
• 2D video acceleration for Windows guests; use the host video hardware for overlay stretching and color conversion (see the manual for more information)
• More flexible storage attachments: CD/DVD drives can be attached to an arbitrary IDE controller, and there can be more than one such drive (the manual for more information)
• The network attachment type can be changed while a VM is running
• Complete rewrite of experimental USB support for OpenSolaris hosts making use of the latest USB enhancements in Solaris Nevada 124 and higher
• Significant performance improvements for PAE and AMD64 guests (VT-x and AMD-V only; normal (non-nested) paging)
• Experimental support for EFI (Extensible Firmware Interface; see the manual for more information)
• Support for paravirtualized network adapters (virtio-net; see the manual for more information)

As far as it concerns myself, teleportation is the feature I was looking forward. Great job, guys.
