I = don=E2=80=99t know if it was this or a previous change in qdisk driver, = but can it be that remote Ceph RBD support is broken?
https://github.com/xen-project/xen/commit/8f486344a00652ed202ad= e43c02c96771812bf8c

Remote network Ceph image works fine with Xen 4.12.x with a = config syntax like this:
disk =3D [ 'format=3Draw, = vdev=3Dxvda1, access=3Drw,backendtype=3Dqdisk, = target=3Drbd:<pool-Name>/<Image-Name>:id=3D<cephx-Id>=E2= =80=98 ]

In = Xen 4.13.0 which I have tested recently it blames with the error message = =E2=80=9Eno such file or directory=E2=80=9C as it would try accessing = the image over filesystem instead of remote network image.

Please help = confirm.


Kind Regards
Jules
