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, root domains, I/O domains, or service domains.
You can configure Oracle Solaris 10 OS with the required patches and packages in guest domains.
Always disable verified boot in each Oracle Solaris 10 guest domain (see Disable Verified Boot on Oracle Solaris 10 Guest 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.
