LVM allows one specify the VG with VG path like "/dev/lv_pool", and

However, if the path is like "/dev/t/lv_pool", the VG name will be
"/t/lv_pool" then, definitely it's not a valid VG name, and LVM will
complain and fail.

Isn't that just a user error for specifying an invalid<path>  for the
target in the XML then ?

If I'm correct, it can be a path of a nest VG.
