RHEL 7.1 supports rbd out of the box; so should be current CentOS 7.

We do not use libvirt storage pool for ovirt, so I don't think you
need to build anything.

Also, we do not access rbd volumes via libvirt. When we run vms using
rbd: volumes, libvirt
pass the volume url to qemu, and qemu access the volume. So we may not
need any rbd
support in libvirt itself.

Did you try to use ceph with ovirt 3.6 on CentOS?
