The roles created on an ESX/ESXi host are separate from the roles created on a vCenter Server system. When
you manage a host using vCenter Server, only the roles created through vCenter Server are available. If you
connect directly to the host using the vSphere Client, only the roles created directly on the host are available.
vCenter Server and ESX/ESXi hosts provide default roles:
System roles
System roles are permanent. You cannot edit the privileges associated with
these roles.
Sample roles
VMware provides sample roles for convenience as guidelines and suggestions.
You can modify or remove these roles.
You can also create completely new roles.
All roles permit the user to schedule tasks by default. Users can schedule only tasks they have permission to
perform at the time the tasks are created.
N
OTE
Changes to permissions and roles take effect immediately, even if the users involved are logged in,
except for searches, where permissions changes take effect after the user has logged out and logged back in
again.
Default Roles for ESX/ESXi and vCenter Server
vCenter Server, ESX, and ESXi provide default roles. These roles group together privileges for common areas
of responsibility in a vSphere environment.
You can use the default roles to assign permissions in your environment, or use them as a model to develop
your own roles.
Table 18-1 lists the default roles for ESX/ESXi and vCenter Server.
