Zones (including LX-brand) have a native view of all sockets, cores, and hyperthreads of the physical system. You set CPU affinity by process (or lwp) using the pbind(1M) command.
Although not directly supported by vmadm, you can also use zonecfg to set dedicated-cpu, which will use pooladm/poolcfg to allocate CPUs for the exclusive use of that zone. Be warned though, that if there aren't enough CPUs to fully dedicate to the zone it will fail to boot, and dedicated cpus are unavailable for use by all other zones, including the global zone. I very highly recommend using pbind over dedicated-cpu. It's much more flexible, doesn't require special permission because it can be used within the zone, and doesn't require extra configuration in the global zone. -- Brian Bennett Systems Engineer, Cloud Operations Joyent, Inc. | www.joyent.com <http://www.joyent.com/> > On Aug 18, 2016, at 8:22 PM, 龙白滔 <[email protected]> wrote: > > > Hi, > > We are running SmartOS on a 2-socket Xeon marchine, and would like to > allocate 4 CPUs for a zone.
