You must use only one controller to manage all the elastic virtual switches in a data center or multitenant cloud environment. You must install the pkg:/service/network/evs package and the pkg:/system/management/rad/module/rad-evs-controller package on the system that acts as an EVS controller.
Use the following commands to install the packages:
# pkg install evs # pkg install rad-evs-controller
After you install the rad-evs-controller package, you need to restart the rad:local service to load the EVS controller by using the following command:
# svcadm restart rad:local
