Openstack neutron-linuxbridge-agent 每次重新启动它时都会不断下降并创建 vxlans

Question

我有一个 openstack 基础设施，它由一个控制器、4 个计算、1 个块存储和 1 个对象存储组成。 一切都很顺利，直到昨天我们创建了一个实例并在其上安装了 ansible，目的是运行一个创建 3 个实例（1 个主实例和 2 个工作实例）并在其上提供 k8s 集群的剧本。 现在，我们运行

openstack network agent list

计算上的每个 linuxbridge 代理都已关闭，我们无法通过 ssh 连接到我们的实例。 这是我在

/var/log/neutron/neutron-linuxbridge-agent.log

中发现的唯一错误

我尝试重新启动节点，返回 1 个快照，因为我们在 VMware 上工作，但它再次发生
