Hi, We've a report of F11 qemu segfaulting when using read-only images here: https://bugzilla.redhat.com/497170 Looking at the current code in stable, there is clearly some borkage: - No error handling in bdrv_aio_rw_vector() - No error handling in dma_bdrv_cb()/dma_bdrv_io() - VectorTranslationState is leaked by bdrv_aio_rw_vector_cb() - dma_aio_cancel() is cancelling the wrong aio The rest of Avi's aio cancellation patches actually fixes all these problems. Please apply to stable.
Thanks Mark. I actually cherry picked the patches directly. This is less error prone. Regards, Anthony Liguori
