[Kimchi-devel] [PATCH V2 2/2] List iSCSI targets available for initiator while creating iSCSI Pool

From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com&gt; Here we call libvirt findStoragePoolSources to get the iSCSI targets. Zhou Zheng Sheng aslo provides a method to get the iSCSI targets in commit f163d22e.
