Re: [libvirt] [PATCH 0/3] qemu: Fix race condition between block jobs and the end of migration

When migrating both memory and storage, we need to make sure block jobs are finished after the virtual CPUs get paused at the end of migration but before QEMU completes the migration otherwise QEMU may die with _co_do_pwritev: Assertion `!(bs->open_flags & 0x0800)' failed This is a libvirt side of the QEMU fix from Dr. David Alan Gilbert: http://lists.nongnu.org/archive/html/qemu-devel/2017-10/msg04895.html Applicable on top of my "Preparation for new QEMU migration states" series I sent yesterday.
