Commit bf32462b missed initializing sdl.opengl. Without the initialization, libvirtd will be terminated by an assert from libxl: Assertion `!libxl_defbool_is_default(db)' failed. Reported-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Jim Fehlig <jfehlig@suse.com> --- Perhaps bending the "trivial rule" a bit, but this patch is trivial and should have been included in bf32462b. I simply forgot to add initialization of sdl.opengl before pushing bf32462b. I'll push this fix shortly. src/libxl/libxl_conf.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 55bd21b..53f327b 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -1243,6 +1243,7 @@ libxlMakeVfb(virPortAllocatorPtr graphicsports, case VIR_DOMAIN_GRAPHICS_TYPE_SDL: libxl_defbool_set(&x_vfb->sdl.enable, 1); libxl_defbool_set(&x_vfb->vnc.enable, 0); + libxl_defbool_set(&x_vfb->sdl.opengl, 0); if (VIR_STRDUP(x_vfb->sdl.display, l_vfb->data.sdl.display) < 0) return -1; if (VIR_STRDUP(x_vfb->sdl.xauthority, l_vfb->data.sdl.xauth) < 0) -- 1.8.4.5
