This is mainly related to librados and librbd on your system. Qemu talks
to librbd which then talks to librados.
Qemu -> librbd -> librados -> Ceph cluster
So make sure you keep the librbd and librados packages updated on your
hypervisor.
When upgrading them make sure you either Stop/Start or Live Migrate the
VMs to a different hypervisor so the VMs are initiated with the new code.
