Hi, 144 is exactly the number of cores on your physical nodes. The scheduler uses the available CPUs (cf. onehost list) and whatever CPU resources are defined in your template.
You could reduce CPU to X<1 to allow overcomitting of physical CPUs.

I have a cluster of three machines, each with 256GB of RAM and 48 cores. I deployed 200 VM instances using occi-compute, and all 200 intances show up in "onevm list". However, OpenNebula does not appear to be willing to actual boot more than 144 of these instances at a time. After there were 144 running instances, no more were started; when I killed one of the running instances, a new one started. I am creating these instances as myself, rather than as the "oneadmin" user. I thought that perhaps some sort of quota mechanism was kicking in, but I can't see anywhere that such a limit is defined. /etc/one/auth/auth.conf looks like this: :database: sqlite://auth.db :authentication: simple :quota: :enabled: false :defaults: :cpu: 10.0 :memory: 1048576 :num_vms: And I've never used the "oneauth quota ..." command. -- Lars Kellogg-Stedman <l...@seas.harvard.edu> Senior Technologist Harvard University SEAS Academic and Research Computing (ARC) _______________________________________________ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org _______________________________________________ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
