[libvirt] [PATCH v3 09/11] docs, tests: Add schema, description, and tests for NFS namespace

Wed Jan 16 01:09:20 UTC 2019


Modify the storagepool.rng to allow for the usage of a different
XML namespace to parse the netfs_mount_opts to be included with
the netfs storage pool definition.

Modify the storagepoolxml2xmltest to utilize a properly modified
XML file to parse and format the namespace for a netfs storage pool.

+    <h3><a id="StoragePoolNamespaces">Storage Pool Namespaces</a></h3>
+
+    <p>
+      Usage of Storage Pool Namespaces provides a mechanism to provide
+      pool type specific data in a free form or abitrary manner via
+      XML syntax targeted solely for the needs of the specific pool type
+      which is not otherwise supportable via XML. For the "netfs" pool
+      this provides a mechanism to provide additional mount options on the
+      command line not listed/supported for the <code>mount_opts</code>
+      element.
+    </p>
+    <dl>
+      <dt><code>netfs:mount_opts</code></dt>
+      <dd>Provides an XML namespace mechanism to optionally utilize
+        specifically named options for the mount command via the "-o"
+        option for the <code>netfs</code> type storage pools. That are
+        not provided by the <code>mount_opts</code> element. In order
+        to designate that the Storage Pool will be using the mechanism,
+        the <code>pool</code> element must be modified to provide the
+        XML namespace attribute syntax as follows:
+
+        <p>
+        xmlns:netfs='http://libvirt.org/schemas/storagepool/source/netfs/1.0'
+        </p>
+
+        <p>
+        The <code>netfs:mount_opts</code> defines the mount options by
+        specifying multiple <code>netfs:option</code> subelements with
+        the attribute <code>name</code> specifying the mount option to
+        be added. The value of the named option is not checked since
+        it's possible options don't exist on all distributions. It is
+        expected that proper and valid options will be supplied for the
+        target host.
+        </p>
+
+        The following XML snippet shows the syntax required in order to
+        utilize
+      <pre>
