It appears that the actual problem is not with "virt-copy-out" specifically, but with the 'guestfish' which it relies on. Running this on 1.36.13 (Ubuntu) fails: # guestfish ><fs> add-drive deb8.img ><fs> run ><fs> tar-out / - | tar tf - libguestfs: error: file receive cancelled by daemon tar: This does not look like a tar archive tar: Exiting with failure status due to previous errors Whereas running the above on guestfish 1.39.9 from git does not produce that error.
