控制器节点已重新启动，并且一些虚拟机正在运行。此后，当登录 Horizon 时，我不断收到以下错误：错误：无法检索实例。我再也看不到正在运行的虚拟机。以下是/var/log/apache2/error.log。我是初学者，我不知道该如何解决这个问题，如果能得到任何帮助我将不胜感激。

答案1
您需要检查所有其他 openstack 服务是否正在运行，例如 nova、neutron 等。systemctl status openstack-nova-api.service应该显示 nova-api 是否正在运行（负责管理虚拟机的服务）。还请检查所有其他服务。通常，服务应已启用，以便重新启动即可启动它们。如果未启用，请启用它们，例如systemctl enable --now openstack-nova-api.service。该--now标志还会在服务停止时启动它。您是如何部署此环境的？如果使用 kolla 或其他部署方法部署，命令可能会有所不同。
