You need to install the following packages before using EVS:
pkg:/service/network/evs
You need to install the core package pkg:/service/network/evs on the EVS manager, EVS controller, and EVS nodes.
When you install the pkg:/service/network/evs package, a new user, evsuser is created. The evsuser is a specific user with the Elastic Virtual Switch Administration rights profile. This profile provides all the required authorizations and privileges to perform EVS operations.
pkg:/system/management/rad/module/rad-evs-controller
You need to install this package only on the system that acts as an EVS controller. You must use only one controller to manage all the elastic virtual switches in a data center or multitenant cloud environment.
