From e0d03b8ceb52e390b8b0a5db1762a8435dd8a44e Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Fri, 14 Aug 2015 18:56:44 +0100 Subject: ui: convert VNC startup code to use SocketAddress The VNC code is currently using QemuOpts to configure the sockets connections / listeners it needs. Convert it to use SocketAddress to bring it in line with modern QAPI based code elsewhere in QEMU. Reviewed-by: Eric Blake Signed-off-by: Daniel P.
