Since d5895fcb (iscsi: Split URL into individual options), creating
qcow2 image on an iscsi LUN fails:
qemu-img create -f qcow2 iscsi://$SERVER/$IQN/0 1G
qemu-img: iscsi://$SERVER/$IQN/0: Could not create image: Invalid
argument
The problem is iscsi_open now expects that transport_name, portal and
target are already parsed into structured options by
iscsi_parse_filename, but it is not called in iscsi_create.

Doesn't the below change make this qdict_put() superfluous?

You are right, bdrv_iscsi.bdrv_needs_filename is false.

Thanks, dropped the qdict_put() for "filename" and applied to my block
