Why does libxl now allow script= with backend=tap|qdisk? See tools/libxl/libxl_device.c:disk_try_backend. Ideally the script should prepare the backend storage based on info from target=. Then the script should report either the dentry to be used by qemu back to libxl, or it should setup the "physical-device" entry to be used by blkback. Right now the target= info is passed to the script, but its also used as ->pdev_path for qemu. Obvisouly qemu cant possibly make sense of the target= info, because its meant for the script=. tools/libxl/check-xl-disk-parse has some script examples. I think right now its not possible to boot an HVM guest from iscsi, for example. Should the logic in libxl be changed to make scripts= more useful, and let libxl read info for qemu which has to be provided by the script?
