I don't think there's any great answers here. Could you do the partition selection outside libguestfs? If it was a plain (not LUKS) partition then the answer would be yes, easily, with nbdkit-partition-filter: https://libguestfs.org/nbdkit.1.html#Combining-plugins-and-filters nbdkit also supports LUKS, but only LUKS v1, not the more common v2.
