Hi,

I'm developing a new datastore driver for Equallogic iSCSI devices.

Testing the clone feature, seems the Source field of the new image is filled with the datastore real path, but must be filled with the destination value echoed from the clone script:

Source image:
Name: test01
Source: 172.30.0.1:iqn.2001-05.com.equallogic:0-8a0906-d3b445203-ed60016ef1250005-test01
Path: --

Cloned image:
Name: test05
Source: /var/lib/one/datastores/104
Path: 172.30.0.1:iqn.2001-05.com.equallogic:0-8a0906-d3b445203-ed60016ef1250005-test01

Source value in the cloned image must be 172.30.0.1:iqn.2001-05.com.equallogic:0-8a0906-ad4445203-2500016ef2a50051-test05, but /var/lib/one/datastores/104 is stored. Correct value is returned at the end of the clone script, as shown in the log

The clone operation seems to ignore the extra parameters shown at the CLONE SUCCESS log message. I don't know if the iscsi datastore driver is also affected for this behavior (i can't test it).

This error makes unusable the cloned image, as the source field points to the datastore path at /var/lib/one, not to the host:target needed to locate the image.

I hope to end development of the eqlscsi datastore driver and the eqliscsi transfer driver in the next days. Almost finished, now testing all the functions with the new 3.6 release and ironing the last bugs.

Best regards,
