It seems that the following commit for libvirt fixed the problem.

live migration with storage encounter assert(!(bs->open_flags &
Status in QEMU:
The vm guest runs a iotest program, and i migrate it with virsh
--copy-storage-all,then the qemu process on the source host happens to
crash with the following message:
kvm: block/io.c:1543: bdrv_co_pwritev: Assertion `!(bs->open_flags & 0x0800)'
2017-08-24 11:43:45.919+0000: shutting down, reason=crashed
here is the release:
qemu 2.7 & 2.10.rc3 were tested.
libvirt 3.0.0 & 3.2.0 were tested.
src_host:virsh migrate --verbose --live --persistent --copy-storage-all
Possible Reason: After bdrv_inactivate_all() was called, mirror_run
coroutine still writes the left dirty disk data to remote nbd server,
which triggers the assertion. But I don't known how to avoid the
problem, help is needed! Thanks.
