Installing the 'vagrant-libvirt' plugin. This can take a few minutes...
Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:
 
An error occurred while installing ruby-libvirt (0.5.2), and Bundler cannot continue.
Make sure that `gem install ruby-libvirt -v '0.5.2'` succeeds before bundling.
 
Warning: this Gemfile contains multiple primary sources. Using `source` more than once without a block is a security risk, and may result in installing unexpected gems. To resolve this warning, use a block to indicate which gems should come from the secondary source. To upgrade this warning to an error, run `bundle config disable_multisource true`.Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
