From: Taimoor Mirza <tmi...@codesourcery.com> 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. Problem is discussed in http://lists.gnu.org/archive/html/qemu-devel/2013-04/msg03089.html
