If RPC services are not running, the following message is displayed when you attempt to start aregcmd:

Login to aregcmd fails with the message: 400 Login failed

Installing Cisco Access Registrar on LDoms

Server virtualization is partitioning of network servers into several independent execution environments. Server virtualization allows a data center to be viewed and managed as a set of compute resources rather than a room of individual systems.

Server virtualization feature in CAR will enable maximum resource utilization with dynamic resource allocation between LDoms.

Note To know about configuration of CAR on LDoms, see White Paper under CAR Collateral in http://wwwin-nmbu.cisco.com/fieldportal/products/car/summary.cfm?Prod=car&tsession.
