From 75c70e37bc4a6bdc394b4d1b163fe730abb82c72 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Mon, 9 Dec 2013 16:03:49 +0100 Subject: spice: stop server for qxl hard reset Hard reset can happen at any time. We should be able to put qxl into a known-good state no matter what. Stop spice server thread for reset so it can't be confused by fetching stale commands lingering around in the rings while we reset is ongoing.
