Patches 2 and 4 fix some bugs related to the close callback handling on the source libvirt side. Patch 3 ensures that the VM on the source libvirt does not get into an invalid state if its migration is aborted during disk mirroring. > > All patches are independent of one another and can be applied separately. > > Michael Chapman (4): > qemu: fix crash in qemuProcessAutoDestroy > qemu: fix error propagation in qemuMigrationBegin > qemu: fix race between disk mirror fail and cancel > util: fix removal of callbacks in virCloseCallbacksRun > > src/qemu/qemu_domain.c | 5 +++++ > src/qemu/qemu_migration.c | 12 +++++++++++- > src/qemu/qemu_process.c | 4 +++- > src/util/virclosecallbacks.c | 10 ++++++---- > 4 files changed, 25 insertions(+), 6 deletions(-) ACK to patches 1 - 3.
