为什么在docker中运行openstack容器时会出现“Watchdog: BUG: Soft lockup CPU”错误

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 horizo​​n 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
