Disable the Logical Domains Manager from the control domain.
primary# svcadm disable ldmd
Disabling the Logical Domains Manager does not stop any running domains, but does disable the ability to create a new domains, change the configuration of existing domains, or monitor the state of the domains.
If you disable the Logical Domains Manager, this disables some services, such as error reporting or power management. In the case of error reporting, if you are in the factory-default configuration, you can reboot the sole domain to restore error reporting. However, this is not the case with power management. In addition, some system management or monitoring tools rely on the Logical Domains Manager.
