With S10U4, a zone with dedicated CPUs gets its own, unshared temporary pool. This example would work if the system had many more CPUs than a V445. A temporary pool only exists while the zone is running. When the zone stops, its dedicated CPUs are made available for assignment to other pools. Also, you can "set ncpus=2" without setting a minimum and maximum. -------------------------------------------------------------------------- Jeff VICTOR Sun Microsystems jeff.victor @ sun.com OS Ambassador Sr. Technical Specialist Solaris 10 Zones FAQ: http://www.opensolaris.org/os/community/zones/faq -------------------------------------------------------------------------- _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
