Oracle VM Server for SPARC 2.0 released

We've just released version 2.0 of Oracle VM Server for SPARC (previously known as LDoms). This is a major new release of our SPARC virtualization technlogy. Here are just some of the new features:
  • Memory Dynamic Reconfiguration - resize your domain's memory while Solaris is running
  • Direct I/O - You can now assign individual PCI-E I/O devices to any domain
  • Affinity Binding for CPUs - optimizes placement of allocated strands onto cores to minimize unnecessary sharing of cores between domains
  • Support for Full Core Allocation - Optionally allocate CPU resources at the core, rather than strand, granularity. Guarantees only full cores are allocated to the domain, while enforcing a cap.
  • Improvements to domain migration performance and the relaxation of certain restrictions
  • Improvements to virtual disk multipathing to handle end-to-end I/O path failures between guest domain and storage device
  • More robust system restoration from XML files: the restoration of the primary domain can now be automated as well
  • Important fixes to MAC address assignment and more robust MAC address collision detection
  • New virtinfo(1) command and libv12n(3LIB) library to extract virtualization info from Solaris 10 9/10 or later
  • New power management capabilities on SPARC T3 based platforms

In addition, there are numerous smaller improvements and bug fixes. The official product documentation has all the details.

Oracle VM Server for SPARC 2.0 runs on all supported SPARC T-Series servers (i.e. T2, T2 Plus & T3 based platforms), including the just-announced SPARC T3 systems. As of this writing, version 2.0 is fully qualified on the T3-1 server (which is now available to order). We will announce full support for our other servers (including the existing UltraSPARC T2 and T2 Plus based platforms) in the coming weeks as we complete our qualification activities.
