与libvirt的Vagrant当地箱子

我已经为libvirt创建了基本框图像，添加框成功了，它在框列表中可见。

[root@centos7 vagrant]# vagrant box list
rhmaster (libvirt, 0)
[root@centos7 vagrant]#

但是当试图流浪时，抱怨盒子不存在。

[root@centos7 vagrant]# vagrant up --provider=libvirt
Bringing machine 'default' up with 'libvirt' provider...
==> default: Uploading base box image as volume into libvirt 
storage...
The box 'rhmaster' does not exist. Please double check and
try again. You can see the boxes that are installed with
`vagrant box list`.

任何指导都非常有用。

我的metadata.json文件：

 {
 "provider"    : "libvirt",
 "format"      : "qcow2",
 "virtual_size" : 30
 }

我的Vagrantfile在框图片中添加：

  Vagrant.configure("2") do |config|
     config.vm.provider :libvirt do |libvirt|
          libvirt.driver = "kvm"
          libvirt.host = 'localhost'
          libvirt.uri = 'qemu:///system'
          libvirt.username = 'root'
          libvirt.connect_via_ssh = true
     end
     config.vm.define :new do |rhmaster|
           rhmaster.vm.box = "rhmaster"
           rhmaster.vm.provider :libvirt do |domain|
               domain.memory = 2048
           end
     end
  end

我的错误文件名box.img有未知字符。我想由于我的终端控制台来自XDCMP会话。现在好了。
