I think this makes sense. As a matter of getting changes in
libguestfs it's better to propose patches and APIs. You could test
this out by adding rsync to appliance/packagelist.in, and then adding
some APIs to libguestfs (see [0] and example [1]). Post the patches
here and we can review them.
Can I put in a vote for rsync as well? I think it would be a very
useful addition to guestfs.
I'm not sure how a streaming network protocol like rsync is going to fit
in to guestfs's command/response protocol though. A generic method for
forwarding TCP to qemu (host? guest? what's it called?) might be good,
and also allow other commands that are implemented over a TCP/IP
transport to be added as well.
