[openstack-dev] [Neutron]Connecting a VM from one tenant to a non-shared network in another tenant

I thought that creating a qport would be enough but it looks like I still missing something else.
I have commented in /opt/stack/quantum/neutron/api/v2/base.py in the create function the ._validate_network_tenant_ownership call.
I can now as an Admin user, can create a qport from tenant-a that is mapped to a private network in tenant-b.
The following still fails with ERROR: The resource could not be found. (HTTP 404) ...
nova boot --flavor 1 --image <image-id> --nic port-id=<port-id>
Where <port-id> is the one I got from the port-create
Any ideas where I should look next?

is what you're trying to do tantamount to creating a port on a network whose tenant_id is different from the network's tenant_id?
We have at the moment a fairly strict ownership check - which does not allow even admin users to do this operation.
I do not have a strong opinion against relaxing the check, and allowing admin users to create ports on any network - I don't think this would constitute a potential vulnerability, as in neutron is someone's manages to impersonate an admin user, he/she can make much more damage.

We are providing load balancing services via virtual machines running under an admin tenant that needs to be connected to VMs attached to a non-shared/private tenant network.
The virtual machine fails to be provisioned connected to the private tenant network event if it is provisioned using the admin user which has admin role on both tenants.
