Oracle VM Server for SPARC (LDoms) release 2.2 came out on May 24. You can get the software, see the release notes, reference manual, and admin guide here on the Oracle VM for SPARC page.

Oracle VM Server for SPARC enables you to create multiple virtual systems on a single physical system.Each virtual system is called alogical domain and runs its own instance of Oracle Solaris 10 or Oracle Solaris 11.

The version of the Oracle Solaris OS software that runs on a guest domain is independent of the Oracle Solaris OS version that runs on the primary domain. So, if you run the Oracle Solaris 10 OS in the primary domain, you can still run the Oracle Solaris 11 OS in a guest domain, and if you run the Oracle Solaris 11 OS in the primary domain, you can still run the Oracle Solaris 10 OS in a guest domain

In addition to that starting with the Oracle VM Server for SPARC 2.2 release you can migrate guest domain even if source and target machines have different processor type.

You can migrate guest domain from a system with UltraSPARC T2+ or SPARC T3 CPU to a system with a SPARC T4 CPU.The guest domain on the source and target system must run Solaris 11 In order
to enable cross CPU migration.In addition to that you need to change the cpu-arch property value on the source system.

For more information about Oracle VM Server for SPARC (LDoms) with Solaris 11 and Cross CPU Migration refer to the following white paper
