If you plan to configure Oracle VM Server for SPARC on this server, follow these guidelines:
Do not configure the Oracle Solaris 10 OS in the control domain.
You can configure Oracle Solaris 10 OS with required patches and packages in the guest, I/O, root, and service domains.
Be aware that instances of Oracle Solaris 10 with required patches and packages in a single guest domain are limited to 1024 virtual CPUs and 4 TBytes of memory.
The majority of a physical domain's memory can be assigned to logical domains. However, a small portion of the PDomain's memory is preassigned to software components, the hypervisor, and certain I/O devices. To determine which portions of the memory are unavailable for logical domains, log in to the PDomain and type this command:
# ldm ls-devices -a mem
In the command output, look for the rows that include _sys_ in the Bound column. These portions of memory are not available for logical domains.
See Oracle Solaris 10 OS Patches for required patches and packages.
