If what you really want to do is access SSH servers, how about using nbdkit-ssh-plugin instead? It is very well tested. https://libguestfs.org/nbdkit-ssh-plugin.1.html > 2.

It must be something in curl. If you really want to use curl (not nbdkit-ssh-plugin which I'd recommend instead), then you'll need to enable curl debugging, ie. adding some of these flags: https://libguestfs.org/nbdkit-curl-plugin.1.html#DEBUG-FLAGS > Please tell me if there are patches that solve this problem. > Thanks, Nikita Pavlov.
