Packer 超时等待 VirtualBox 的 SSH 错误

Question

虽然我可以在 VirtualBox 中手动 ssh，但 Packer 不知道 ssh 连接是否建立。
我遇到过同样的问题，但找不到任何解决方案。
我使用 packer 的目的是将我现有的 ovf 文件转换为 Digital Ocean droplet，以便我可以在我的 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构建

Answer 1

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

有2种解决方案：
1) 删除 /etc/udev/rules.d/70-persistent-net.rules 以获得新的 MAC 地址或
2) 将 eth0 名称更改为 eth1，例如 eth1、eth2、eth3

执行上述任一方法后，通过键入 reboot 重新启动来宾系统。

检查ifconfig -a
您将看到 eth0 或您选择的其他以太网名称。
