Subject: [PATCH] Add unit tests for new specification of nvram.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds unit tests for remote NVRAM.

Examples:

<nvram type='network'>
  <source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/0'>
    <host name='example.com' port='6000'/>
    <auth username='myname'>
      <secret type='iscsi' usage='mycluster_myname'/>
    </auth>
  </source>
</nvram>

and

<nvram type='network'>
  <source protocol='nbd' name='bar'>
    <host name='example.org' port='6000'/>
  </source>
</nvram>

and

<nvram type='file'>
  <source file='/var/lib/libvirt/nvram/guest_VARS.fd'/>
</nvram>
