Are you referring to the fact that a zone with one-half of the shares in its pool would not receive 50% of the CPU power in that pool over an arbitrarily short period of time, e.g. 1 millisecond? Or are you referring to something else? > -- Renaud > > -------- Original Message -------- > Subject: Re:[zones-discuss] zones and cpu shares > From: Renaud Manus <[EMAIL PROTECTED]> > To: Niklas Jonsson <[EMAIL PROTECTED]> > Cc: zones-discuss@opensolaris.org > Date: Thu Jul 19 2007 12:39:53 GMT+0200 (CEST) > >> -------- Original Message -------- >> Subject: [zones-discuss] zones and cpu shares >> From: Niklas Jonsson <[EMAIL PROTECTED]> >> To: zones-discuss@opensolaris.org >> Date: Thu Jul 19 2007 10:58:44 GMT+0200 (CEST) >> >>> Hi, >>> >>> I have 5 zones on my machine, >>> >>> I would like to change the cpu-shares for all these machines to look like >>> this: >>> >>> machine 1, Should have a minimum of 50% cpu share available all the time >>> >>> machine 2-5, share the rest of the resources. >>> >>> If I do this with pools (since this is a V445 with 4 cpu's) that would mean, >>> >>> machine gets 2 cpu's, machine 2-5 only shares 1 cpu, and the global-zone >>> gets one cpu. >>> >>> Hope someone could explain how to do this. >> $ 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 >> >> -- Renaud >> -- -------------------------------------------------------------------------- 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
