[Libguestfs] iSCSI initiator iqn

Hi, I could not find any option to set iSCSI initiator iqn while using guestfish, although the underlying qemu command has this option. It appears that each time guestfish tries to connect to iSCSI LUN, a randomly generated initiator iqn is being used. This is preventing guestfish to connect to the iSCSI target in our environment as the target allows incoming connection based on the preconfigured initiator iqn. Is there way to set iSCSI initiator iqn with guestfish command? Regards Raghu
