Packer-plugin-qemu，尽管选择了 qcow2 格式，但 Box 的类型为 raw

完成后packer build，当我检查它的文件格式时，尽管选择了 qcow2 格式，qemu-img但virt-install两者都告诉我文件格式是原始格式。

打包器构建命令之后立即执行 qemu-img 命令

$ sudo qemu-img info output/bastillebox-installer-box_qemu_archlinux-2023-05.qcow2
image: ./bastillebox-installer-box_qemu_archlinux-2023-05.qcow2

virtual size: 1.42 GiB (1522309120 bytes)

    filename: ./bastillebox-installer-box_qemu_archlinux-2023-05.qcow2
    protocol type: file

为什么是打包插件 qemu尽管我已经这样配置了，但没有生成 qcow2 格式的盒子？

答案1

后处理器创建一个 vagrant box 文件。
我不知道如何处理这个问题，但至少这给出了问题的答案。

  post-processor "vagrant" {
    output = "output/${local.vm_name}_${source.type}_${source.name}-${formatdate("YYYY-MM", timestamp())}.qcow2"
    vagrantfile_template = "templates/vagrantfile.tpl"
  }
