在新虚拟机上调用 createhd 时，vagrant up 失败并出现错误 VERR_ALREADY_EXISTS

Question

我使用下面的 Vagrantfile 作为许多新 VM 的基础(我将其复制到新目录)，但今天在创建磁盘时，新 VM 无法正确配置并出现错误 VERR_ALREADY_EXISTS。磁盘文件(本地 vagrant 'tmp' 目录中的 source_code_disk.vdi )在开始时肯定不存在，并且实际上是在 vagrant 启动期间创建的，但 'createhd' 似乎认为它已经存在，尽管 FileExists 检查这意味着它不存在当“createhd”调用时存在。有趣的是，如果我“vagrant destroy”新虚拟机，那么磁盘文件也不会被删除。在基于相同 Vagrantfile 且工作正常的其他安装中，磁盘文件都是在“vagrant up”期间创建的，并通过“vagrant destroy”删除的。运行“vagrant up --debug”不会产生任何额外的信息，为了简洁起见，我没有在此处包含输出。

    config.vm.box = "ubuntu/trusty32"

    config.ssh.forward_agent = true

    config.vm.provision :shell do |shell|
        shell.inline = "sudo chsh -s /bin/bash vagrant"
    end

    # create a disk for the source code
    config.vm.provider "virtualbox" do | v |
        unless File.exist?(file_to_disk)
            v.customize ['createhd', '--filename', file_to_disk, '--size', 50 * 1024]
            v.customize ['storageattach', :id, '--storagectl', 'SATAController', '--port', 1, '--device', 0, '--type', 'hdd', '--medium', file_to_disk]
        end
    end    

end

已修复:通过更改相对路径名来删除前导“./”

file_to_disk = 'tmp/source_code_disk.vdi'

我删除了磁盘文件路径中的“./”，并且可靠地失败的安装现在可以顺利完成 - 我怀疑在使用以无害分隔符为前缀的相对路径时存在路径检查失败以及一些计时问题'./'

# -*- mode: ruby -*-
# vi: set ft=ruby :

file_to_disk = 'tmp/source_code_disk.vdi'

Vagrant.configure("2") do |config|

    config.vm.box = "ubuntu/trusty32"
    config.vm.network "private_network", ip: "192.168.33.11"
    config.vm.hostname = "testdisk"
    config.ssh.forward_agent = true
    config.ssh.shell = "/bin/bash -l"

    config.vm.provision :shell do |shell|
        shell.inline = "sudo chsh -s /bin/bash vagrant"
    end

    # create a disk for the source code
    config.vm.provider "virtualbox" do | v |
        unless File.exist?(file_to_disk)
            v.customize ['createhd', '--filename', file_to_disk, '--size', 50 * 1024]
            v.customize ['storageattach', :id, '--storagectl', 'SATAController', '--port', 1, '--device', 0, '--type', 'hdd', '--medium', file_to_disk]
        end
    end    

end

注意:原始文件在大多数情况下都有效，但时不时地当我将文件复制到新目录并尝试“vagrant up”时，我无法配置虚拟机。我知道这听起来不太可能，但这是真的，这里的调试显示了如果我“vagrant destroy”然后仅从文件路径中删除“./”则有效的失败 - 没有其他更改。
