Virtual host bus adapters (starting with Oracle VM Server for SPARC 3.3).

Each domain also has the following resources: Every domain runs its own instance of Oracle Solaris 11 or Solaris 10, just as if each had its own separate physical server. Oracle VM Server for SPARC creates virtual machines, which are usually called domains. Oracle VM Server for SPARC is available on supported SPARC processors without additional license or hardware costs. At this writing, as many as 4096 CPU threads can be supported in a single M7-16 server. The chip technology is integral to Oracle VM Server for SPARC, which leverages the large number of CPU threads available on these servers. These processors include the Oracle SPARC M5-32, M6-32, M7, S7, T4, T5, and T7 servers and blades older SPARC T3 servers Sun SPARC Enterprise T5x20/T5x40 servers Sun Blade T6320/T6340 server modules and Fujitsu SPARC M10 servers. Oracle VM Server for SPARC is available on systems based on SPARC chip multithreading technology (CMT) processors. It is an ideal way to consolidate multiple complete Oracle Solaris systems onto a modern powerful SPARC server.

It permits operation of virtual machines with less overhead than traditional designs by changing the way guests access CPU, memory, and I/O resources.

Oracle VM Server for SPARC (formerly called Logical Domains) is a virtualization technology that creates SPARC virtual machines, also called domains.
