VirtualBox 3.1 Officially Released

Earlier this month we talked about new VirtualBox 3.1 features when this Sun virtualization platform was still in beta, but this morning VirtualBox 3.1 final is now out the door for those interested in Windows, Linux, and Solaris virtualization. VirtualBox 3.1 adds support for teleportation (live migration of VMs between hosts), VM states can now be restored from arbitrary snapshots, network attachments can now be changed on active VMs, and support for more flexible storage attachments.

VirtualBox 3.1 also brings major performance enhancements for PAE and x86_64 guests when running atop a system with Intel VT-x or AMD-V processor technology with normal, non-nested paging. A few other changes for VirtualBox 3.1 include rewrite of experimental USB support for OpenSolaris hosts, experimental support for EFI (Extensible Firmware Interface), and para-virtualized network adapters are now supported.

The VirtualBox 3.1 release announcement can be read on vbox-announce, the complete list of changes can be found on the Wiki, and version 3.1.0 can be downloaded at VirtualBox.org.
