openstack pike 启动实例报:Host 'controller' is not mapped to any cell

郑全

错误：实例 "sztech1" 执行所请求操作失败，实例处于错误状态。: 请稍后再试 [错误: Host 'controller' is not mapped to any cell].

原因是没有映射主机,解决办法:
执行以下命令后解决:

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

实际执行结果:

[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
Found 2 cell mappings.
