Hi,
with qemu (2.4.1), if I do an internal snapshot of an rbd device,
then I pause the vm with vm_stop,
the qemu process is hanging forever
monitor commands to reproduce:
# snapshot_blkdev_internal drive-virtio0 yoursnapname
# stop
I don't see this with qcow2 or sheepdog block driver for example.

this could look like the problem I have recenty trying to
fix with dataplane enabled. Patch series is named as
[PATCH for 2.5 v6 0/10] dataplane snapshot fixes

anyway, even if above will not help, can you collect gdb
traces from all threads in QEMU process. May be I'll be
able to give a hit.
