Hi George, If you configure RamWeigher and set ram_weight_multiplier to <0 then the scheduler will automatically order the hypervisors by remaining ram (the hypervisor with least ram will be selected first). You may want to implement your own weigher to order your hypervisors in specific ways. (also check out http://docs.openstack.org/kilo/config-reference/content/section_compute-scheduler.html and look for the section of weights) Thanks, Xinyuan ---------- Forwarded message ---------- From: Georgios Dimitrakakis <giorgis at acmac.uoc.gr> Date: Mon, Jul 20, 2015 at 6:27 AM Subject: [Openstack] Scheduler Order To: openstack at lists.openstack.org Hello! I would like to know if it's possible to define the order on which the hypervisors are loaded. I already have in my configuration ram_weight_multiplier = -1.0 in order to pack as many VMs in one hypervisor as possible. What I would like to know now is if I can somehow define the order of the hypervisors since there are differences among them.
