   This morning I got some time to work the block-iscsi script. With
some tweaking I was able to call directly the script with something like:

          scripts/block-iscsi add
iqn=bla,portal=bla,username=bla,password=bla
     
   and I was also able to simulate the remove. To do so I had to comment
out some variables (XENBUS_PATH for example).

   Now I'm trying to test it at domain creation time, and to do so I had
to uncomment XENBUS_PATH and the other changes. Creating the domain with
the disk using the iscsi syntax [1] fails. In the xen log file I get an
error complaining about XENBUS_PATH not being set [2].

   I was hoping that XENBUS_PATH would be set by the xl toolstack. Am I
doing anything wrong?

   Best,

   Gustau

[1] disk =
['script=block-iscsi,vdev=xvda,target=iqn=iqn.2015.local.labs-entel.test_xen:target1,portal=10.0.2.20,username=bla,password=bla']
[2] XENBUS_PATH: parameter null or not set
