No special configuration, I followed this guide: http://docs.openstack.org/havana/install-guide/install/apt/content/ No HA... It is a very basic setup BTW... 1 controller, 1 network node, 2 compute nodes. Environment Inspired by: https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst 3) When that happens, could you check with neutron CLI that the network > does really exist? > Which commands precisely do you think I need to check? For example: --- root@controller:~# neutron net-show bb43d3f0-8c1a-4844-aaac-7068a6771588 +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | True | | id | bb43d3f0-8c1a-4844-aaac-7068a6771588 | | name | Americanet - A85 - 4 Mbps | | provider:network_type | vxlan | | provider:physical_network | | | provider:segmentation_id | 1 | | router:external | True | | shared | False | | status | ACTIVE | | subnets | 5d40ee39-6da8-48b4-a028-3cdd6ec329cf | | tenant_id | f3d729002af648088718dfa15b106fb2 | +---------------------------+--------------------------------------+ --- neutron net-external-list # yes, it shows my external network neutron net-list # yes, it shows all my networks, 1 external, X tenants subnets neutron router-list # yes, it shows all my routers # Tenant Router that triggered the Dashboard error (BTW, all tenants are currently facing the very same problem): root@pcuaa-1:~# neutron router-show f572af38-cc50-4c9f-b863-5a167c0ec3d3 +-----------------------+-----------------------------------------------------------------------------+ | Field | Value | +-----------------------+-----------------------------------------------------------------------------+ | admin_state_up | True | | external_gateway_info | {"network_id": "bb43d3f0-8c1a-4844-aaac-7068a6771588", "enable_snat": true} | | id | f572af38-cc50-4c9f-b863-5a167c0ec3d3 | | name | Router #1 | | routes | | | status | ACTIVE | | tenant_id | 0a1a0228f84648c3a39f190212ab147b | +-----------------------+-----------------------------------------------------------------------------+ See it?! External Network IS there. I don't know why Dashboard is unable to retrieve its info/status. 4) If it 3 == NO, could you check it's on the database itself? > If == YES they exists but, nevertheless, where should I check on the database (db / tables)?
