Minikube安装在Ubuntu vm_VT-X/AMD-v中,可以在另一个VM内部启用VM

Question

我想在Ubuntu vm中安装minikube(在虚拟框中).我为vm启用了VT-X/AMD-v.但是我得到了以下错误.

# minikube start
Starting local Kubernetes cluster...
E0217 15:00:35.395801    3869 start.go:107] Error starting host: Error creating host: Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory".

 Retrying.
E0217 15:00:35.396019    3869 start.go:113] Error starting host:  Error creating host: Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
================================================================================
An error has occurred. Would you like to opt in to sending anonymized crash
information to minikube to help prevent future errors?
To opt out of these messages, run the command:
    minikube config set WantReportErrorPrompt false

我找到了一个参考,据我所知,我们不能在虚拟化中进行虚拟化.这是真的吗？我怎样才能解决这个问题？

使用Docker直接在VM上运行Minikube,并且不需要嵌套虚拟化的"none"驱动程序选项.

设置none驱动程序选项:

[root@minikube ~]# minikube config set vm-driver none

按照VM OS版本的说明安装Docker-ce.

最后运行minikube启动:

[root@minikube ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@minikube ~]# systemctl start docker
[root@minikube ~]# minikube start

===================
WARNING: IT IS RECOMMENDED NOT TO RUN THE NONE DRIVER ON PERSONAL WORKSTATIONS
        The 'none' driver will run an insecure kubernetes apiserver as root that may leave the host vulnerable to CSRF attacks

When using the none driver, the kubectl config and credentials generated will be root owned and will appear in the root home directory.
You will need to move the files to the appropriate location and then set the correct permissions.  An example of this is below:

        sudo mv /root/.kube $HOME/.kube # this will write over any previous configuration
        sudo chown -R $USER $HOME/.kube
        sudo chgrp -R $USER $HOME/.kube

        sudo mv /root/.minikube $HOME/.minikube # this will write over any previous configuration
        sudo chown -R $USER $HOME/.minikube
        sudo chgrp -R $USER $HOME/.minikube

This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true
Loading cached images from config file.

Answer 2

Virtual Box不支持嵌套虚拟化中的VT-X/AMD-v.在virtualbox.org上查看此打开的票证/功能请​​求.

关于SO讨论这个 主题,还有一些问题和答案.

可能的解决方案:

1. 如前所述:在嵌套虚拟化中使用支持VT-X/AMD-v 的其他虚拟机管理程序(如Xen,KVM或VMware).
2. 在主机操作系统上安装Minikube,而不是在虚拟机中安装.

Answer 3

尝试在没有嵌套虚拟化的情况下运行minikube（应安装docker）：

minikube start --vm-driver=none

从Kubernetes 文档中：

Minikube还支持--vm-driver = none选项，该选项在主机而不是VM中运行Kubernetes组件。使用此驱动程序需要Docker和linux环境，但不需要管理程序。
