Rather predictably this has broken libvirt on i686 and armv7hl (ie. 32 bit arches):
DEBUG util.py:439: - package libvirt-daemon-driver-storage-4.10.0-1.fc30.i686 requires libvirt-daemon-driver-storage-rbd = 4.10.0-1.fc30, but none of the providers can be installed DEBUG util.py:439: - conflicting requests DEBUG util.py:439: - nothing provides librados.so.2 needed by libvirt-daemon-driver-storage-rbd-4.10.0-1.fc30.i686
I filed a bug, against libvirt since it appears that no client library for ceph will be forthcoming:
