[fedora-virt] install to new lvm storage pool fails

Thanx for the earlier kickstart help, for some reason my brain kept
 farting me into interpreting :'path' as directory path and not the
 fully qualified file path.
 Attached is the virt-install debug.
 The XML appears correct to me mapping the new allocation to hda as the
 first definition, but only seems to find the hdb  iso/dvd pseudo drive.
 I have also tried scsi and virtio bus types to no avail.
 Is this a bug I shoud file or another I/O error (Inept/Operator)

 Assuming things were working correctly would the bus=scsi or
 bus=virtio give perceptibly better performance?
