I think the problem we are having is that we added "VMAdmin" to the delete port rule.
We have this: "owner": "tenant_id:%(tenant_id)s", "admin_or_vm_admin_owner": "role:admin or (tenant_id:%(tenant_id)s and role:VMAdmin)", "admin_or_vm_admin_network_owner": "role:admin or (tenant_id:%(network:tenant_id)s and role:VMAdmin)", "vm_admin_owner_or_vm_admin_network_owner": "rule:admin_or_vm_admin_network_owner or rule:admin_or_vm_admin_owner", ... "delete_port": "rule:vm_admin_owner_or_vm_admin_network_owner or rule:context_is_advsvc", So it takes VMAdmin to delete a port, but the user in this case did not have that role when deleting an instance. I'm going to reopen this bug to see if nova can change to use admin to delete the port, if the neutron port binding extension is enabled. ** Changed in: nova Status: Invalid => New ** Changed in: nova Assignee: (unassigned) => Chuck Carmack (chuckcarmack75) -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1540939 Title: Instance delete causing port leak Status in OpenStack Compute (nova): New Bug description: Nova can cause a neutron port leak after deleting an instance. If neutron has the port binding extension installed, then nova uses admin credentials to create the port during instance create: https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py#L537 However, during instance delete, nova always uses the user creds: https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py#L739 Depending on the neutron policy settings, this can leak ports in neutron. Can someone explain this behavior? We are running on nova kilo.
