From ab902981cf4d46834d82eb095f2b9ab159e017bf Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 7 Sep 2012 21:48:22 +0200 Subject: [PATCH] qxl: Ignore set_client_capabilities pre/post migrate The recent introduction of set_client_capabilities has broken (seamless) migration by trying to call qxl_send_events pre (seamless incoming) and post (*) migration, triggering the following assert: qxl_send_events: Assertion `qemu_spice_display_is_running(&d->ssd)' failed. The solution is easy, pre migration the guest will have already received the client caps on the migration source side, and post migration there no longer is a guest, so we can simply ignore the set_client_capabilities call in both those scenarios. *) Post migration, so not fatal for to the migration itself, but still a crash Signed-off-by: Hans de Goede Signed-off-by: Gerd Hoffmann --- hw/qxl.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/hw/qxl.c b/hw/qxl.c index 0176b1a..e539134 100644 --- a/hw/qxl.c +++ b/hw/qxl.c @@ -953,6 +953,11 @@ static void interface_set_client_capabilities(QXLInstance *sin, { PCIQXLDevice *qxl = container_of(sin, PCIQXLDevice, ssd.qxl); + if (runstate_check(RUN_STATE_INMIGRATE) || + runstate_check(RUN_STATE_POSTMIGRATE)) { + return; + } + qxl->shadow_rom.client_present = client_present; memcpy(qxl->shadow_rom.client_capabilities, caps, sizeof(caps)); qxl->rom->client_present = client_present; -- 2.7.4
