在Docker中运行openstack容器时，为什么会出现“Watchdog：BUG：Soft lockup CPU”错误。

我刚刚部署了使用kolla和kolla-ansible stable / pike版本的openstack。 我部署在一个控制节点和一个计算节点上。 它工作，但是当我尝试使用地平线仪表板时，控制节点非常缓慢，locking和terminal输出以下内容：

每当我停止在控制节点上运行的所有Docker容器时，似乎没有更多的CPUlocking错误，但是一旦我启动所有在控制节点上运行OpenStack服务的Docker容器，它就会开始运行再次慢，locking错误再次开始
