我目前使用的 openstack testlab（单节点设置）遇到了一些问题。我用 ansible 部署了它，在我添加一个额外的计算节点之前没有任何问题。在我重新启动服务器之前，openstack 没有显示任何错误，但重新启动后，当我执行时出现以下错误nova service-list

答案1
我们在从 Kilo 升级到 Liberty 时遇到了这个问题。我们进行了以下修复：
在 nova 数据库上我们运行了：
select id,host,deleted,forced_down from services ;
这导致一些服务forced_down的价值为NULL。
为了修复我们运行：
update services set forced_down=0 where id in (list of ids from earlier query);
