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 first patch would fix the default case when we use the machine 'xenfv'. But we can also use the machine 'pc' and I don't know how to fix this case. The second and third patches are a step in the direction of fixing migration with the machine 'pc'. I have not look at save/restore for PV guest yet. Thanks, Anthony PERARD (3): migration: Fix regretion for xenfv machine. migration: Fix global state with Xen. migration: Add configuration section to vmstate with xen. hw/i386/pc_piix.c | 3 +++ include/migration/migration.h | 1 + migration/migration.c | 7 +++++++ migration/savevm.c | 6 ++++++ 4 files changed, 17 insertions(+) -- Anthony PERARD
