List, Paolo, Please find a patch that plugs libiscsi as a possible target for SCSI-GENERIC, allowing a guest passthrough access to talk to the remote iscsi devices directly.
When specifying a -drive that uses iscsi:// as well as setting if=scsi this passes all SCSI commands straight to iscsi and the remote target just like for /dev/sg* devices. Example: ./x86_64-softmmu/qemu-system-x86_64 -m 1024 -enable-kvm -cdrom /linuxmint-12-gnome-dvd-64bit.iso -device lsi -drive file=iscsi://10.1.1.125/iqn.ronnie.test/1,if=scsi,bus=0,unit=6 regards ronnie sahlberg
