[Kimchi-devel] [PATCH V4 5/5] Storagepool SCSI/FC: Modifies mockmodel and implements tests for FC pool

Rodrigo Trujillo rodrigo.trujillo at linux.vnet.ibm.com
Wed Feb 5 14:18:38 UTC 2014


This patch modifies the Mock model functions to allow user to create a
SCSI FC pool in test environment. Then implements functions to test
API and rest.
