 Review comment:
   @kiwiflyer Instead of tr and cut, can you improve string processing (maybe use more predictable sed/awk like simply do this `grep $path | awk '{print $1}'`  if you only want the target device, like vda, vdb etc.)? I'm concerned if different versions of libvirt or different distributions may give a different kind of output.
