I'm attempting to use qemu-kvm (qemu-kvm-ev-2.12.0-44.1.el7_8.1) to run a VM that will be able to use an iscsi volume that has been encrypted with LUKS. Below are the qemu command line arguments related to this volume:
-object secret,id=scsi1-0-0-1-luks-secret0,file=/root/qemuluks.key \ -drive file.driver=iscsi,file.portal=$TARGET_IP:3260,file.target=$TARGET_IQN,file.lun=0,file.transport=tcp,file.initiator-name=iqn.1994-05.com.redhat:host1,key-secret=sec0,format=luks,if=none,id=drive-scsi1-0-0-1 \ -device scsi-block,bus=scsi1.0,channel=0,scsi-id=0,lun=1,drive=drive-scsi1-0-0-1,id=scsi1-0-0-1 \ When running the VM with qemu-kvm, I get the following error: 2021-09-22T20:26:04.975007Z qemu-kvm: -device scsi-block,bus=scsi1.0,channel=0,scsi-id=0,lun=1,drive=drive-scsi1-0-0-1,id=scsi1-0-0-1: cannot get SG_IO version number: Operation not supported Is this a SCSI device? I think that it is at least using the key since if I intentionally provide an incorrect value for the key I get a different error about "Invalid password, cannot unlock any keyslot" but it gets further with the correct key. Is it supported to use LUKS with the iscsi driver and libiscsi? If so, are there any other configuration options I should be considering? Thanks, Will
