Is this a CentOS 6 host machine as well? Usually that error message means that
qemu doesn't recognized the device name libvirt requested, in this case
usb-storage. And indeed I'm pretty sure that we disable usb-storage at build
time for RHEL6.

If you are just trying to install to a physical usb stick, attach it to the VM
as a regular disk device and _not_ usb storage.
