[Libvirt-cim] [PATCH 2 of 2] [TEST]#2 Adding new test RPCS/10_create_storagevolume.py

# HG changeset patch # User Deepti B. Kalakeri <deeptik(a)linux.vnet.ibm.com&gt; # Date 1251350089 25200 # Node ID 7fa9b3a3bca5106d4f4a16278ca9169816a44526 # Parent bd5411ebb634f6cf0945aa4e2f6896eb4221c03f [TEST]#2 Adding new test RPCS/10_create_storagevolume.py Patch 2: -------- 1) Added code to verify the StoVol template RASD. 2) Seperated the SDC query into a function. 3) Used the default_disk_pool for DIR type pools This test verifies the creation of StorageVol in the dir pool. Tested with KVM on F11 with current sources. Signed-off-by: Deepti B.
