# HG changeset patch
# User Kaitlin Rupert <karupert at us.ibm.com>
# Date 1265142620 28800
# Node ID f74f985dfa2a4427ebbde3ab117b2b37463dd762
# Parent  3655b03ada11d9e99a1d10b97aaa7cdb737fc493
[TEST] #2 Verify that user can specify target dev for network interfaces

Updates:
  -Fix typo is error message
  -Start guest after defining it
  -Generate a random number to use in the NIC target device name. This will
   help ensure the device name is unique.

+# Purpose:
+#   Verify provider's support for specifying the target device for vNICs 
+#
+# Steps:
+#  1) Build RASD parameters, making sure to specify target device for network
+#     interface 
+#  2) Create guest
+#  3) Verify guest is defined properly
