Boot2Docker启动失败

Question

我对码头工人来说是全新的.我从Source安装了它.我试图通过使用从cmd运行它boot2docker start.但我得到以下内容

boot2docker start
     Failed to start machine boot2docker-vm <run again with v for details> 

boot2docker init
     virtual machine boot2docker-vm already exists

boot2docker start
     Failed to start machine boot2docker-vm exit status:1

所以,对你们来说,这将是一个简单的问题.我不知道该怎么办.我试过SO.但我无法理解解决方案,所以我没能实现它.请提供一些建议

编辑:我希望它会有所帮助.bios中有一些东西被禁用了.

Answer 1

原因:

您需要在错误日志中注意的信息块是

  Waiting for VM "boot2docker-vm" to power on...
  VBoxManage.exe: error: **VT-x is disabled in the BIOS.**(VERR_VMX_MSR_VMXON_DISABLE
  D)

这意味着您当前工作站的BIOS设置阻止了CPU上其他操作系统的虚拟化.Docker在您的计算机上运行虚拟Linux操作系统,因此这就是问题所在.

对于英特尔芯片,虚拟化功能通常称为VT-x或类似的东西.对于AMD芯片,虚拟化功能称为AMD-V.我使用的是像你这样的英特尔芯片,所以这个解决方案适用于英特尔芯片.

解:

关闭电源并进入BIOS并启用VT-x.在我的BIOS中,联想Thinkpad T440,需要更改的设置在Security-> Virtualization下.

打开电源并返回到您的C:/path/to/Boot2Docker for Windows文件夹.

运行boot2docker delete以确保没有VM正在运行.

运行boot2docker init以初始化VM.

运行boot2docker start以创建一个新的Docker虚拟机!

要访问Docker VM,请运行,boot2docker ssh因为从版本1.5.0开始,Docker Client不能在Windows上运行.
