I've created diskpool.conf file in EAFP.01 patch as follows. Any other
file have to be created?

+def conf_file():
+    """
+       Creating diskpool.conf file.
+    """
+    try:
+        f = open(disk_file, 'w')
+        f.write('%s %s' % (test_dpath, '/'))
+        f.close()
+    except Exception,detail:
+        Globals.logger.error("Exception: %s", detail)
+        status = SKIP
+        sys.exit(status)
+
+def clean_up_restore():
+    """
+        Restoring back the original diskpool.conf
+        file.
+    """
+    try:
+        if os.path.exists(back_disk_file):
+            os.remove(disk_file)
+            move_file(back_disk_file, disk_file)
+    except Exception, detail:
+        Globals.logger.error("Exception: %s", detail)
+        status = SKIP
+        sys.exit(status)

 If the libvirt 0.4.0 or newer, the disk pool is supported. But why I can't
 get th diskpool ID by wbemein?  There is none output of wbemein below(the
libvirt
 version is 0.4.1 on my test machine):

 wbemein http://root:password@localhost:5988/root/virt:KVM_DiskPool

  The patch for KVM & XenFV support are all passed on my test machine,
which
  is set up by F9, the libvirt version is either 0.4.0 or 0.4.1. So I don't
  reproduce the failing. Maybe I'm still in the confusion of how to make
this
  patch work correctly, would you please give more detail instruction or
  add another patch for it?

  Thanks!
