minikube status返回

WARNING: Your kubectl is pointing to stale minikube-vm.
To fix the kubectl context, run `minikube update-context`

我已经使用这个驱动程序几个星期了，直到昨天它运行良好，没有任何错误。我尝试重新启动 docker 守护进程和服务，但问题仍然存在。

编辑
在以后的尝试中，我设法在没有任何更改的情况下启动了机器，但是启动需要相当长的时间(5-10 分钟)。关于为什么会发生这种情况的任何想法？

此问题的解决方案是在您的 GRUB 引导参数中启用 IOMMU。
您可以通过在/etc/default/grub 中设置以下内容来做到这一点
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on"
如果您使用的是 AMD 处理器，则应将 amd_iommu=on 附加到引导参数中
GRUB_CMDLINE_LINUX_DEFAULT="安静飞溅 amd_iommu=on"
然后运行 ​​update-grub 并重新启动
