From efcb7e45290ecc8633f7c5bdf02ac86f6289fa7d Mon Sep 17 00:00:00 2001 From: Taimoor Mirza Date: Thu, 15 Aug 2013 23:13:28 +0500 Subject: slirp: Port redirection option behave differently on Linux and Windows port redirection code uses SO_REUSEADDR socket option before binding to host port. Behavior of SO_REUSEADDR is different on Windows and Linux. Relaunching QEMU with same host and guest port redirection values on Linux throws error but on Windows it does not throw any error.
