unregister_netdevice：等待 vethd8a9cb4 释放（vethd8a9cb4 不存在）

我目前正在笔记本电脑上试验 kubernetes 和 docker，我遇到了一个问题，当我尝试在我的计算机上启动 hyperkube 时，它​​会永远无法启动（或者它会启动，但我无法启动其中的容器），并且我的 /var/log/syslog 充满了如下日志行：

Sep  8 16:51:36 <hostname> kernel: [ 1848.979278] unregister_netdevice: waiting for vethd8a9cb4 to become free. Usage count = 1

我知道vethdocker 使用接口（kubernetes 使用接口）让容器相互通信，我的理解是我应该能够找出使用该接口的内容ip -d link show，但是，它并没有显示这个特定的接口：

有人知道这是什么意思吗？ syslog 引用不在 中的 veth 接口是正常的吗ip link show？ 我该如何释放这个 veth 设备？

就此而言：

据我所知，这是一个内核错误（https://github.com/docker/docker/issues/5618), Kube 在 1.2 版本中通过将容器桥标记为混杂来解决此问题。如果不重新启动，则无法恢复。 Hyperkube 只会采用 docker0 上存在的任何设置，因此您也可以使 docker0 成为 promisoucs（ip link set docker0 promisc on）。
