I doubt many people have tried this, because 1) cinder/nova/glance probably do the job well in a multi-tenant fashion 2) you’re poking holes into your ceph cluster security.
Anyway, if you still want it, you would need (I guess) have to create a provider network that will be allowed to access your ceph network.
You can either route it from your current public network, or create another network. It’s 100% up to you, and not osa specific.

Hi osa team,
i have a multimode openstack-ansible deployed, ocata 15.1.3, with ceph as backend for cinder (with our own ceph infra).
After create an instance with root volume, i would like to mount a ceph block or cephfs directly to the vm (not a cinder volume). So i want to attach a new interface to the vm that is in the ceph vlan.
How can i do that ?
We have our ceph vlan propagated on bond0 interface (bond0.xxx and br-storage configured as documented) for openstack infrastructure.
Should i have to propagate this vlan on the bond1 interface where my br-vlan is attach ?
Should i have to use the existing br-storage where the ceph vlan is already propagated (bond0.xxx) ? And how i create the ceph vlan network in neutron (by neutron directly or by horizon) ?
Has anyone ever experienced this ?
