Internal cloud that is used for Power KVM CI single use VMs: AvailabilityZoneFilter AggregateMultiTenancyIsolation RetryFilter RamFilter ComputeFilter ComputeCapabilitiesFilter ImagePropertiesFilter CoreFilter NumInstancesFilter * NUMATopologyFilter NumInstancesFilter is a custom weigher I have added that returns negative number of instances on a host. Using it this way gives an even spread of instances over the compute nodes up to a point the compute cores are filled up evenly, then it overflows to the compute nodes with more CPU cores. Maybe it is possible to achieve the same with existing filters, at the time I did not see how. --- Mikhail Medvedev IBM _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
