如何从头构建libvirt盒

Question

我正试着从头开始做一个流浪汉的小盒子。

我安装了ubuntu14.04，并使用这教程为流浪者准备了机器，然后我使用命令virsh domblklist test查找我的图像文件，所以我在这里找到了/var/lib/libvirt/images/test.img，然后复制到要打包我的盒的地方。然后，我用qcow2命令将原始图像文件转换为这格式(因为这页面说只有qcow2格式支持)。最后，为了完成任务，我执行了vagrant init test并创建了metadata.json文件

{
  "provider"     : "libvirt",
  "format"       : "qcow2",
  "virtual_size" : 8
}

然后，我使用命令tar cvzf vltest.box ./metadata.json ./Vagrantfile ./box.img将所有内容放在一个框中。然后我用vagrant box add test.img test给流浪汉加了一个盒子。

然后我试着用

vagrant init test
vagrant up --provider=libvirt

但它被困在这里：

...
==> default:  -- Video VRAM:        9216
==> default:  -- Keymap:            en-us
==> default:  -- INPUT:             type=mouse, bus=ps2
==> default:  -- Command line : 
==> default: Creating shared folders metadata...
==> default: Starting domain.
==> default: Waiting for domain to get an IP address...

然后我决定打开机器，这就是我看到的：

这里是原始机器配置：

更新:我也尝试过封隔器，但是当grub出现时会得到相同的错误。这是我的封隔器模板：

{
    "builders":
    [
      {
        "type": "qemu",
        "iso_url": "/home/galiaf95/Downloads/ubuntu-14.04.3-desktop-amd64.iso",
        "iso_checksum": "cab6dd5ee6d649ed1b24e807c877c0ae",

        "disk_interface": "virtio"
      }
    ],
    "post-processors": [
        {
            "keep_input_artifact": false,
            "output": "box/ubuntu-1404-server.box",
            "type": "vagrant"
        }
    ]
}

ISO文件的ubuntu14.04我从ubuntu网站下载。

所以我的问题是：

1. 我做错了什么以及如何解决
2. 有没有更好的方法从零开始建造流浪的libvirt盒子

Answer 1

我做错了什么以及如何解决

真的帮不了我的忙

有没有更好的方法从零开始建造流浪的libvirt盒子

我建议使用封隔器作为V 0.7.2打包器支持的迷走性-libvirt。
