X-Received-From: 209.132.183.28 Cc: mprivozn@redhat.com, Yonit Halperin , kraxel@redhat.com Subject: [Qemu-devel] [PATCH 4/4] spice: adding seamless-migration option to the command line 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 The seamless-migration flag is required in order to identify whether libvirt supports the new QEVENT_SPICE_MIGRATE_COMPLETED or not (by default the flag is off). New libvirt versions that wait for QEVENT_SPICE_MIGRATE_COMPLETED should turn on this flag. When this flag is off, spice fallbacks to its old migration method, which can result in data loss.
