package Homestead box wrong: The Vagrant virtual environment you are trying to package must be powered off
<p>when i package Homestead-box:</p>

<pre><code>➜  Homestead git:(master) vagrant halt
➜  Homestead git:(master) vagrant package --output h-0417.box
The Vagrant virtual environment you are trying to package must be powered off.
➜  Homestead git:(master) vagrant box list
coreos-alpha      (virtualbox, 509.1.0)
coreos-alpha      (virtualbox, 522.0.0)
laravel/homestead (virtualbox, 0.4.2)
➜  Homestead git:(master) vagrant package --output h-0417.box --base laravel/homestead.box
==&gt; laravel/homestead.box: VM not created. Moving on...
➜  Homestead git:(master) pwd
/Users/qk/Homestead
➜  Homestead git:(master) vagrant --version

</code></pre>

<p>and i continue to uninstall some parallel plugin and restart osx it meets the same error :</p>

<pre><code>vagrant plugin uninstall vagrant-parallels

➜  Homestead git:(master) vagrant package --output h-0418.box
The Vagrant virtual environment you are trying to package must be powered off.
➜  Homestead git:(master) pwd
/Users/qk/Homestead
➜  Homestead git:(master) ls
LICENSE.txt   composer.json homestead     init.sh       scripts
Vagrantfile   composer.lock init.bat      readme.md     src
</code></pre>

<p>is there some logs or how to checkout some other plugin is installed to cause this error.</p>
