A domain is a container that consists of a set of virtual resources for a guest operating system. The Logical Domains Manager provides the command-line interface (CLI) for creating, configuring, and managing the domains. The Logical Domains Manager and the Oracle VM Server for SPARC MIB support the following virtual resources:
CPUs
Memory
Disk, network, and console I/O
Cryptographic units
The Logical Domains Manager exports an XML-based control interface to the Oracle VM Server for SPARC MIB. The Oracle VM Server for SPARC MIB parses the XML interface and populates the MIB. The Oracle VM Server for SPARC MIB only provides support for the control domain.
The Oracle VM Server for SPARC MIB polls the Logical Domains Manager periodically for updates or status changes, and then issues SNMP traps to the system management applications.
If the Oracle VM Server for SPARC MIB can no longer allocate a needed resource, the MIB returns a general error to the system management application through the Oracle Solaris SNMP agent (net-SNMP). The SNMP trap-delivery mechanism does not confirm the error. No specific state or checkpointing is implemented in the Oracle VM Server for SPARC MIB. The Oracle Solaris SNMP agent with the Oracle VM Server for SPARC MIB is started and monitored by the init process and the Service Management Facility (SMF). If the Oracle Solaris SNMP agent fails and exits, SMF restarts the process automatically, and then the new process dynamically restarts the Oracle VM Server for SPARC MIB module.
