Oracle today released LDOM 2.0 as Oracle VM Server for SPARC 2.0. This new released features better resource and power management but most importantly it now finally supports dynamic reconfiguration of memory. It should also support more flexible migration of domains in cooperation with Solaris (Cooperative guest migration) but it does not, as expected, seem to be the full live migration that we are eagerly awaiting. Oracle Solaris 11 Express is also mentioned as a possible OS for a guest domain, no news that it will work but interesting that it's mentioned. An the new SPARC T3 processor is of course supported in this new release.
