Hi,
What would be the best way/easiest way to limit an amount of a 8core CPU to a
specific zone.
Can I do it in such a way to limit 2 of 8 cores, or does it have to be in a
percentage bases.
Im assuming it would be done with zonecfg, any help is appreciated.
Project Duckhorn (Solaris Express >= b55) makes this pretty easy -
zonecfg has been extended to support new keywords, so you just have
to :
zonecfg -z somezone
add dedicated cpu
set ncpus=2-8
end
and reboot the zone.
From the zonecfg manpage:
dedicated-cpu: ncpus, importance
The number of CPUs that should be assigned for this
zone's exclusive use. The zone will create a pool and
processor set when it boots. See pooladm(1M) and
poolcfg(1M) for more information on resource pools. The
ncpu property can specify a single value or a range (for
example, 1-4) of processors. The must be enough free
processors to allocate to this zone when it boots or the
zone will not boot. The processors assigned to this zone
will not be available for the use of the global zone or
other zones. This resource is incompatible with the pool
property. Only a single instance of this resource can be
added to the zone.
