Re: [Libguestfs] [nbdkit PATCH] nbd: Add new nbd forwarding plugin

This is a minimal implementation of an NBD forwarder; it lets us convert between old and newstyle connections (great if a client expects one style but the real server only provides the other), or add TLS safety on top of a server without having to rewrite that server. Right now, the real server is expected to live on a named Unix socket, and the transactions are serialized rather than interleaved; further enhancements could be made to also permit TCP servers or more efficient transmission. I also envision the possibility of enhancing our testsuite to use NBD forwarding as a great test of our server. Signed-off-by: Eric Blake <eblake(a)redhat.com&gt;
