Logical Domains 1.2 Release Notes

Required Software and Patches

This section lists the required software and patches for use with LDoms 1.2 software.

Required and Recommended Solaris OS

To use all the features of LDoms 1.2 software, the operating system on all domains should be at least equivalent to the Solaris 10 5/09 OS. This can be either a fresh or upgrade installation of the following:

Note –

The Logical Domains 1.2 software is supported on the OpenSolaris OS starting with the OpenSolaris 2009.06 release. The Logical Domains 1.2 documentation focuses on the use of Logical Domains on the Solaris 10 OS. The same Logical Domains features are available for both the Solaris 10 OS and the OpenSolaris OS. However, you might encounter slight differences when using Logical Domains with the OpenSolaris OS. For more information about the OpenSolaris OS, see the OpenSolaris Information Center.

Required Solaris 10 5/09 Patches

Following are the required Solaris 10 5/09 patches for use with LDoms 1.2 software. An X marks whether a patch must be installed on that specific type of domain, but the patches can be applied to all domains.

Note –

This patch list includes the minimum required patch revisions. You can install later revisions of the same patch.

Minimum Version of Software Required

It is possible to run the LDoms 1.2 software along with previous revisions of the other software components. For example, you could have differing versions of the Solaris OS on the various domains in a machine. To take advantage of all features of Logical Domains 1.2, ensure that your logical domains run Solaris 10 5/09 plus the patches listed in Table 1–1. Note that you can run different OS releases in each logical domain on the same system. For those domains that run earlier versions of the OS, you might not have all the features that are available in Logical Domains 1.2. However, an alternate upgrade strategy could be to upgrade the control and service domains to Solaris 10 5/09 plus the patches listed in Table 1–1 and to continue running the guest domains at the existing patch level.

Following is a matrix of the minimum versions of software required. The LDoms 1.2 package, SUNWldm, can be applied to a system running at least the following versions of software. The minimum software versions are platform specific and depend on the requirements of the CPU in the machine. The minimum Solaris OS version for a given CPU type applies to all domain types (control, service, I/O, and guest).
