Dynamic pools pretty much have to be enabled to associate a pset with a
zone, don't they?  So if I set pset.min=1, pset.max=2, it will run with
1 CPU because I don't have a resource optimization objective?  Just
trying to make sure I understand this.  thanks.

Subject: Re: [zones-discuss] dynamic pool objective, default

There is no default objective. Each pset will have at least the minimum
number of CPUs, but may have more. No pset, other than the default pset,
can have more CPUs than pset.max. The number of CPUs allocated to a set
will not change unless someone intervenes manually (e.g. by transferring
a CPU between sets) or a resource optimisation objective is set and
dynamic pools are enabled.

If you want more details about libpool's allocation strategy take a look


In particular the comment at line 902 for the pset_allocate_imp()
function should be enlightening.

pretty simple.  If i set up pools for each zone with associated
processor sets, each with a pset.min and pset.max, but don't set a
dynamic pool objective, is there a default objective?  or do the zones
run with the minimum specified number of cpu's and never change?
