OpenSolaris 2009.06 is launched at CommunityOne West, San Francisco, on June 1 2009.

One of the new features or technologies is that now, OpenSolaris can run, and is supported, on UltraSPARC machines, which of course also
includes the Sun T-Series servers, with the UltraSPARC T[1,2,2+] chips.

Why is that important ?

That means you now can configure and run Logical Domains, or LDoms, on an OpenSolaris 2009.06 machine, and use this OS as control, service, or guest domain.

Watch a short demo in the below screencast, how you can use LDoms, and underlying ZFS, to very rapidly create new guest domain, or virtual machines, and therefore application services. This demo is also shown at pod # 340 during CommunityOne and JavaOne.
