Less than three weeks after the beta, Sun Microsystems has announced the release of version 3.1.0 of its open source VirtualBox desktop virtualisation application for x86 hardware.
The following major new features were added:
- 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)
More details about the release can be found in the Change Log. VirtualBox 3.1.0 is available to download for Windows, Mac OS X, Linux and Solaris. VirtualBox is released under version 2 of the GNU General Public License (GPLv2) and VirtualBox binaries are released under the VirtualBox Personal Use and Evaluation License (PUEL) licence.
