Oracle VM Server for SPARC Guidelines

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.
