This section describes how to use the fair share scheduler (FSS) with zones.
FSS CPU shares for a zone are hierarchical. The shares for the global and non-global zones are set by the global administrator through the zone-wide resource control zone.cpu-shares. The project.cpu-shares resource control can then be defined for each project within that zone to further subdivide the shares set through the zone-wide control.
To assign zone shares by using the zonecfg command, see How to Set zone.cpu-shares in the Global Zone. For more information on project.cpu-shares, see Available Resource Controls. Also see Using the Fair Share Scheduler on an Oracle Oracle Solaris System With Zones Installed for example procedures that show how to set shares on a temporary basis.
You can use zone.cpu-shares to assign FSS shares for the global zone and for non-global zones. If FSS is the default scheduler on your system and shares are not assigned, each zone, including the global zone, is given one share by default. If you have one non-global zone on your system and you give this zone two shares through zone.cpu-shares, that defines the proportion of CPU which the non-global zone will receive in relation to the global zone. The ratio of CPU between the two zones is 2:1.
