System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones

Share Balance Between Zones

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.
