From edc5cb1a52b2847201acf78b0fba67ab3c2464d5 Mon Sep 17 00:00:00 2001 From: Yonit Halperin Date: Mon, 17 Oct 2011 10:03:18 +0200 Subject: [PATCH] spice: turn client_migrate_info to async RHBZ 737921 Spice client is required to connect to the migration target before/as migration starts. Since after migration starts, the target qemu is blocked and cannot accept new spice client we trigger the connection to the target upon client_migrate_info command. client_migrate_info completion cb will be called after spice client has been connected to the target (or a timeout). See following patches and spice patches.
