From 83f7180227a4c383e00fcbc0c079805557a657c8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Thu, 21 Feb 2019 12:06:55 +0100 Subject: [PATCH] spice: avoid spice runtime assert MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Spice server doesn't like to be started or stopped twice . It aborts with: (process:6191): Spice-ERROR **: 19:29:35.912: red-worker.c:623:handle_dev_start: assertion `!worker->running' failed It's easy to avoid that situation since qemu spice_display_is_running tracks the server state. After the commit "spice: do not stop spice if VM is paused", it will be possible to pause and resume the VM, and this will call qemu_spice_display_start() twice. The easiest is to add a check for spice_display_is_running with this patch to avoid the assert.
