From 8cf364898cfe4ae761f2253e91a040633d6f87be Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Thu, 24 Nov 2011 18:10:49 +0100 Subject: vnc: implement shared flag handling. VNC clients send a shared flag in the client init message. Up to now qemu completely ignores this. This patch implements shared flag handling. It comes with three policies: By default qemu behaves as one would expect: Asking for a exclusive access grants exclusive access to the client connecting. There is also a desktop sharing mode which disallows exclusive connects (so one forgetting -shared wouldn't drop everybody else) and a compatibility mode which mimics the traditional (but non-conforming) qemu behavior.
