Re: [libvirt] [PATCH 2/2] Fix migration in text mode and shared storage migration in json mode

The patches for shared storage migration were not correctly written for json mode. Thus the 'blk' and 'inc' parameters were never being set. In addition they didn't set the QEMU_MONITOR_MIGRATE_BACKGROUND so migration was synchronous. Due to multiple bugs in QEMU's JSON impl this wasn't noticed because it treated the sync migration requst as asynchronous anyway. Finally 'background' parameter was converted to take arbitrary flags but not renamed, and not all uses were changed to unsigned int. * src/qemu/qemu_driver.c: Set QEMU_MONITOR_MIGRATE_BACKGROUND in doNativeMigrate * src/qemu/qemu_monitor_json.c: Process QEMU_MONITOR_MIGRATE_NON_SHARED_DISK and QEMU_MONITOR_MIGRATE_NON_SHARED_INC flags * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: change 'int background' to 'unsigned int flags' in migration APIs.
