OK.  Yeah, unfortunately, the error reporting still isn't very good, so it's
hard to figure out what went on.  One of the main reasons I was getting the
above type of error was when the storage pool didn't get defined on the remote
end for whatever reason.  You'll get better information if you log into both the
src and dst hosts, shutdown libvirtd, and run:

# LIBVIRT_DEBUG=1 /usr/sbin/libvirtd --listen --verbose

That will show you better error information.
