The basic reason for this error is described in the FAQ here:

  http://libguestfs.org/guestfs-faq.1.html#whats-the-deal-with-guestfish--i

We need to know what OS is contained in the guest because without that
information we cannot perform some customizations ...

... in this case ‘--root-password’ and ‘--firstboot-command’ are not
possible without knowing the OS.  Specifying a partition name isn't
sufficient.

Pino asked if there is an OS in this image.  From the fact you're
running dpkg-reconfigure I'm going to guess it's Debian/Ubuntu, but
it's strange that inspection cannot detect that.  Are you presenting
all the guest disks to virt-customize?
