* Teleportation (aka live migration); migrate a live VM session from
one host to another
* 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”)
* 2D video acceleration for Windows guests; use the host video hardware
for overlay stretching and color conversion
* More flexible storage attachments: CD/DVD drives can be attached to
arbitrary storage controllers, and there can be more than one such
drive
* 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)
* Support for paravirtualized network adapters (virtio-net)
