$ pooladm -e
$ pooladm -s
$ pooladm -c
$ poolcfg -c 'create pset pset1 (uint.min = 2 ; uint.max = 2)'
$ poolcfg -c 'create pset pset2 (uint.min = 1 ; uint.max = 1)'
$ poolcfg -c 'create pool pool1'
$ poolcfg -c 'create pool pool2'
$ poolcfg -c 'associate pool pool1 (pset pset1)'
$ poolcfg -c 'associate pool pool2 (pset pset2)'
$ pooladm -c
Assuming, the zones are up & running:
$ poolbind -p pool1 -i machine1
$ poolbind -p pool2 -i machine2
$ poolbind -p pool2 -i machine3
$ poolbind -p pool2 -i machine4
$ poolbind -p pool2 -i machine5
To make the bindings persistent, use
$ zonecfg -z <zone> set pool=<pool>
---------------
With latest OpenSolaris builds and upcoming S10U4, you can directly
dedicate the cpus using zonecfg without creating pools.
Eg:
$ zonecfg -z <zone>
add dedicated-cpu
set ncpus=2-2
end
