qemu-kvm: -device scsi-generic,drive=drive-data-disk,id=data-disk,bus=scsi0.0: Device doesn't support drive option werror
qemu-kvm: -device scsi-generic,drive=drive-data-disk,id=data-disk,bus=scsi0.0: Device 'scsi-generic' could not be initialized
/etc/qemu-ifdown: could not launch network script

scsi-generic is not accessible from libvirt (and thus not supported) in RHEL6. Only scsi-block is.
