From 2942e420e06bd6370756ef0f4722dcf8f4c74659 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Mon, 11 Jan 2016 13:17:03 +0000 Subject: sockets: remove use of QemuOpts from socket_connect The socket_connect method accepts a QAPI SocketAddress object which it then turns into QemuOpts before calling the inet_connect_opts/unix_connect_opts helper methods. By converting the latter to use QAPI SocketAddress directly, the QemuOpts conversion step can be eliminated Signed-off-by: Daniel P.
