![为什么在docker中运行openstack容器时会出现“Watchdog: BUG: Soft lockup CPU”错误](https://linux22.com/image/713282/%E4%B8%BA%E4%BB%80%E4%B9%88%E5%9C%A8docker%E4%B8%AD%E8%BF%90%E8%A1%8Copenstack%E5%AE%B9%E5%99%A8%E6%97%B6%E4%BC%9A%E5%87%BA%E7%8E%B0%E2%80%9CWatchdog%3A%20BUG%3A%20Soft%20lockup%20CPU%E2%80%9D%E9%94%99%E8%AF%AF.png)
我刚刚使用 kolla 和 kolla-ansible 稳定版/pike 部署了 openstack。我部署在一个控制节点和一个计算节点上。两个节点都是运行 Centos 7 的 Dell PowerEdge 2950 服务器。部署成功,但当我尝试使用 horizon 仪表板时,控制节点非常慢并锁定,终端输出以下内容:

每当我停止控制节点上运行的所有 docker 容器时,似乎不再出现任何 CPU 锁定错误,但只要我再次启动控制节点上运行 openstack 服务的所有 docker 容器,它就会再次开始运行得非常慢,并且再次出现锁定错误
