In an Oracle VM Server for SPARC environment, console I/O from the primary domain is directed to the service processor (SP). The console I/O from all other domains is redirected to the service domain that runs the virtual console concentrator, vcc. If the service domain runs the Oracle Solaris 11 OS, the guest domain console output can be logged to a file.
Service domains support console logging for logical domains. While the service domain must run the Oracle Solaris 11 OS, the guest domain being logged can run either the Oracle Solaris 10 OS or the Oracle Solaris 11 OS.
The domain console log is saved to a file on the service domain called /var/log/vntsd/domain-name/console-log that provides the vcc service. You can rotate console log files by using the logadm command. See the logadm(1M) and logadm.conf(4) man pages.
The Oracle VM Server for SPARC software enables you to selectively enable and disable console logging for each logical domain. Console logging is enabled by default.
