X-Received-From: 209.132.183.28 Cc: mprivozn@redhat.com, Yonit Halperin , kraxel@redhat.com Subject: [Qemu-devel] [PATCH v3 1/5] spice: notify spice server on vm start/stop X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Spice server needs to know about the vm state in order to prevent attempts to write to devices when they are stopped, mainly during the non-live stage of migration. Instead, spice will take care of restoring this writes, on the migration target side, after migration completes.
