Packer超时等待VirtualBox的SSH错误

Question

尽管我可以在VirtualBox中手动ssh，但Packer不知道是否已建立ssh连接。
我见过同样的问题，但是我找不到任何解决方案。
使用打包程序的目的是将现有的ovf文件转换为Digital Ocean Droplet，以便可以在Digital Ocean服务器中使用它。

template.json

{
  "builders": [
    {
      "type": "virtualbox-ovf",
      "source_path": "/Users/seoyoochan/Desktop/work/G4M_3.1.2_OVF_demo/G4M_centos6_demo.ovf",
      "ssh_username": "root",
      "ssh_password": "g4mg4m$$",
      "boot_command":[
        "root<return>",
        "g4mg4m$$<return>"
      ],
      "headless": true,
      "boot_wait": "30s",
      "ssh_wait_timeout": "10000s",
      "shutdown_command": "echo 'packer' | sudo -S shutdown -P now"
    }
  ],
  "post-processors": ["vagrant"]
}

运行没有调试选项的打包程序生成

Answer 1

发生此错误的原因是因为eth0设备不存在，这是因为新的MAC地址没有被覆盖。

有两种解决方案：
1）删除/etc/udev/rules.d/70-persistent-net.rules以获取新的MAC地址或
2）像eth1 ， eth2 ， eth3一样将eth0名称更改为eth1

按照上述两种方法中的任意一种之后，通过键入reboot来reboot来宾系统。

检查ifconfig -a
您将看到eth0或您选择的其他以太网名称。
