解决Placement API BUG

# vim /etc/httpd/conf.d/00-nova-placement-api.conf
<Directory /usr/bin>
   <IfVersion >= 2.4>
      Require all granted
   </IfVersion>
   <IfVersion < 2.4>
      Order allow,deny
      Allow from all
   </IfVersion>

控制节点

验证配置

$ . admin-openrc

$ openstack hypervisor list

# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

每次添加计算节点都要运行nova-manage cell_v2 discover_hosts

或者可以自动执行

# vim /etc/nova/nova.conf
[scheduler]
discover_hosts_in_cells_interval = 300
