[Kimchi-devel] [PATCH v4 5/5] test_model: test creating iSCSI storage pool

[Zhou Zheng Sheng]

This patch adds iSCSI storage pool test to test_model.test_storagepool.
It firstly checks if there exists an iSCSI target named
"iqn.2013-12.localhost.kimchiUnitTest" on local host. If not, skip the
test; if yes, continue to run the test already defined in test_storagepool.

v2 -> v3
  Do not create dir for the pool, pool.build() called by
  storagepools_create() does this automatically.

v3 -> v4
  No Changes.
