Comment 1 for bug 1763649

@Corey / James - I have no ceph around at all, also this is reported against a cloud-archive qemu (Ocata if I read it correctly).

Can you confirm this issue and if so are there further insights how to handle it further?

@Crazik - to what extend could you try on your existing setup with different qemu&libvirt versions like those of Ubuntu Cloud Archive Pike (2.10) and Queens (2.11) from [1] ?
If you can it might be worth to update the storage node (ceph) independently to the compute node qemu/libvirt - that way more easily we might get a feeling in which area a potential fix might be.
