The following system resources feature has been added to the Solaris 10 10/09 release.
The zones parallel patching enhancement to the standard Solaris 10 patch utilities increases the patching tools performance on systems with multiple zones by allowing parallel patching of the non-global zones. In releases prior to Solaris 10 10/09, the feature is implemented through the patch utilities patch 119254-66 or later revision for SPARC and 119255-66 or later revision for x86. The global zone is still patched before the non-global zones are patched.

When using the Sun xVM hypervisor in a Solaris OS, fully virtualized guest domains are referred to as hardware-assisted virtual machines (HVMs). HVM + PVIO guests provide better performance through the use of PV drivers.
Releases starting with the Solaris 10 10/08 release are shipped with the Solaris PV drivers. A patch is available for Solaris 10 5/08.
