Some other infos:
I can reproduce it too with manual snapshot with rbd command
#rbd --image myrbdvolume snap create --snap snap1
qemu monitor:
#stop
This is with ceph hammer 0.94.5.
in qemu vm_stop, the only thing related to block driver are
bdrv_drain_all();
ret = bdrv_flush_all();

Objet: qemu : rbd block driver internal snapshot and vm_stop is hanging forever
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.
Regards,
Alexandre
