The nbdkit package in Fedora puts its plugins in /usr/lib64/nbdkit/plugins
(not /usr/local) so it seems like you're using a self-compiled package
already. It should work with the package in Fedora, so I would remove
the self-compiled one and use the Fedora one.
Right, this is leftover from Fedora 31, after removing /usr/locla/lib64/nbdkit
and /usr/loca/sbin/nbdkit my test script works, and importing vms using https
works:

But this does not test local import using unix socket.
To test local import, I must run virt-v2v on oVir host, and our only
option now is
rhel 8.3, or centos 8.3 (oVirt dropped Fedora support in 4.4).
I tried to build virt-v2v on rhel 8.3, but I'm missing the ocaml packages
(maybe because I'm using development repos?). I found that ocaml is available
in centos 8.3.
Is it possible to build virt-v2v from git on centos 8.3?
