You'll need to add that to the libguestfs appliance, by adding the package name to appliance/packagelist.in (if building from source) or $libdir/guestfs/supermin.d/packages (if using the system libguestfs package). Note this will only work correctly if the userspace tooling is packaged and installed as a distro package, ie. an RPM or .deb. If they are doing stupid stuff then you'll need to list the files separately in 'hostfiles' which is more complicated. You can check whether or not the right tools get included in the appliance using virt-rescue.
