List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: QEMU-devel Cc: Amit Shah , Anthony PERARD , Juan Quintela , Stefano Stabellini , Xen Devel Hi, We've spotted several regression which prevent migration with Xen using the same version of QEMU or from a previous version of QEMU (tryied with 2.2). Regression have been introduce by at least: - df4b1024526cae3479da3492d6371fd4a7324a03 migration: create new section to store global state - 61964c23e5ddd5a33f15699e45ce126f879e3e33 migration: Add configuration section The last patch fix migration for 'xenfv' machine and for 'pc,accel=xen' machine. 'xenpv' machine is not affected as there is no emulated device state to save. Change since in v2: - replace memcpy() call by a strncpy(). - Move the skip_config_section and the like from 'xenfv' machine init to xen_init() which is called by accel_init_machine. (in 3rd patch) Thanks, Anthony PERARD (3): migration: Fix global state with Xen. migration: Add configuration section to vmstate with xen. migration: Fix regression for xenfv and pc,accel=xen machine. include/migration/migration.h | 1 + migration/migration.c | 7 +++++++ migration/savevm.c | 6 ++++++ xen-common.c | 5 +++++ 4 files changed, 19 insertions(+) -- Anthony PERARD
