hi, the default behavior of nova used to be spread not pack and i belive it still is. the default behavior with placement however is closer to a packing behavior as allcoation candiates are retrunidn in an undefined but deterministic order. on a busy cloud this does not strictly pack instaces but on a quite cloud it effectivly does you can try and enable randomisation of the allocation candiates by setting this config option in the nova.conf of the shcduler to true. https://docs.openstack.org/nova/latest/configuration/config.html#placement.randomize_allocation_candidates on that note can you provide the nova.conf for the schduelr is used instead of the compute node nova.conf. if you have not overriden any of the nova defaults the ram and cpu weigher should spread instances withing the allocation candiates returned by placement. > > [DEFAULT] > osapi_compute_listen = {{ > hostvars[inventory_hostname]['ansible_ens3f1']['ipv4']['address'] }} > metadata_listen = {{ > hostvars[inventory_hostname]['ansible_ens3f1']['ipv4']['address'] }} > enabled_apis = osapi_compute,metadata > transport_url = rabbit://openstack:{{ rabbitmq_pw }}@{{ controller1_ip_man > }}:5672,openstack:{{ rabbitmq_pw }}@{{ > controller2_ip_man }}:5672,openstack:{{ rabbitmq_pw }}@{{ controller3_ip_man > }}:5672 > my_ip = {{ hostvars[inventory_hostname]['ansible_ens3f1']['ipv4']['address'] > }} > use_neutron = True > firewall_driver = nova.virt.firewall.NoopFirewallDriver > [api] > auth_strategy = keystone > [api_database] > connection = mysql+pymysql://nova:{{ nova_dbpw }}@{{ vip }}/nova_api > [barbican] > [cache] > backend=oslo_cache.memcache_pool > enabled=true > memcache_servers={{ controller1_ip_man }}:11211,{{ controller2_ip_man > }}:11211,{{ controller3_ip_man }}:11211 > [cells] > [cinder] > os_region_name = RegionOne > [compute] > [conductor] > [console] > [consoleauth] > [cors] > [crypto] > [database] > connection = mysql+pymysql://nova:{{ nova_dbpw }}@{{ vip }}/nova > [devices] > [ephemeral_storage_encryption] > [filter_scheduler] > [glance] > api_servers = http://{{ vip }}:9292 > [guestfs] > [healthcheck] > [hyperv] > [ironic] > [key_manager] > [keystone] > [keystone_authtoken] > auth_url = http://{{ vip }}:5000/v3 > memcached_servers = {{ controller1_ip_man }}:11211,{{ controller2_ip_man > }}:11211,{{ controller3_ip_man }}:11211 > auth_type = password > project_domain_name = default > user_domain_name = default > project_name = service > username = nova > password = {{ nova_pw }} > [libvirt] > [matchmaker_redis] > [metrics] > [mks] > [neutron] > url = http://{{ vip }}:9696 > auth_url = http://{{ vip }}:35357 > auth_type = password > project_domain_name = default > user_domain_name = default > region_name = RegionOne > project_name = service > username = neutron > password = {{ neutron_pw }} > service_metadata_proxy = true > metadata_proxy_shared_secret = {{ metadata_secret }} > [notifications] > [osapi_v21] > [oslo_concurrency] > lock_path = /var/lib/nova/tmp > [oslo_messaging_amqp] > [oslo_messaging_kafka] > [oslo_messaging_notifications] > [oslo_messaging_rabbit] > [oslo_messaging_zmq] > [oslo_middleware] > [oslo_policy] > [pci] > [placement] > os_region_name = RegionOne > project_domain_name = Default > project_name = service > auth_type = password > user_domain_name = Default > auth_url = http://{{ vip }}:5000/v3 > username = placement > password = {{ placement_pw }} > [quota] > [rdp] > [remote_debug] > [scheduler] > discover_hosts_in_cells_interval = 300 > [serial_console] > [service_user] > [spice] > [upgrade_levels] > [vault] > [vendordata_dynamic_auth] > [vmware] > [vnc] > enabled = true > keymap=en-us > novncproxy_base_url = https://{{ vip }}:6080/vnc_auto.html > novncproxy_host = {{ > hostvars[inventory_hostname]['ansible_ens3f1']['ipv4']['address'] }} > [workarounds] > [wsgi] > [xenserver] > [xvp] > [placement_database] > connection=mysql+pymysql://nova:{{ nova_dbpw }}@{{ vip }}/nova_placement > > what is the problem?
