If I have a machine with a large number of cores (say 24), and

mean that if there's enough stuff running in global that it can
preempt
the stuff running inside the zone? The concern here is that the stuff
we want to run in the zone is a bit more critical than in global, so
we
wouldn't want global to eat up CPU resources of the zone. (I
suppose we
could repurpose the stuff running inside global and the zone, but then
we'd get the reverse isolation issue.)
hi Ray,
the psrinfo behavior that you observe is normal, as the global zone
has access to all system resources. you may try using the poolstat
command as it shows cpu's per pool, cpu's used and load average per
pool.

additionally you can use pooladm to see details about your pools and
pset's and how they are assigned

another idea is to create a second zone, move all the applications
currently running in the global zone to the new onez, and use the
global zone only for administrative purposes (that is if the
applications do not explicitly require to run in a global zone). the
global zone is "powerful" :)
The other questions is that there's an old E450 running Solaris 8 and
it's got a bunch of stuff installed on it. Would it be possible to
somehow convert all the software and data of that E450 into a
container
or zone and run that on a more modern machine - say a T5420 which runs
Solaris 10 (without upgrading the stuff running under the E450 to
Solaris 10?)
regarding the above question - there is a solution specially for this
- Solaris 8 and Solaris 9 containers (it was called project Etude)
