Moving here my comment since it's marked with "alert" and was escalated too: =============================================================================== I have this issue reproduced on CI dev system right now, ping me for getting access to the system to debug (@sshnaidm on #tripleo) The failed vm networks are located in non-master HA controller node, maybe it was switch during the creation, or before it. So far as I see, the router has its gateway down: (overcloud) [jenkins@undercloud tripleo-ci]$ openstack port list --router 71ce23d9-2c47-4286-ad56-f2e5265ee30f +--------------------------------------+----------------------------------------------+-------------------+------------------------------------------------+--------+ | ID | Name | MAC Address | Fixed IP Addresses | Status | +--------------------------------------+----------------------------------------------+-------------------+------------------------------------------------+--------+ | 5597935b-ce81-4002-ba83-1fdd404fab45 | HA port tenant | fa:16:3e:8e:24:c3 | ip_address='169.254.192.7', subnet_id | ACTIVE | | | 124a61db46a24ebbadda7caa47de29a1 | | ='3af6b6be-972a-4fe5-bdc8-717a24a623a4' | | | 9e9131b5-31b4-44f3-92e0-7b13de9e7f8d | | fa:16:3e:07:3e:15 | ip_address='192.168.2.1', subnet_id='086fe45e- | ACTIVE | | | | | 4c20-45ae-bc16-ad7bb370951f' | | | b72a3c4b-6545-4b34-856d-904b4bd66694 | HA port tenant | fa:16:3e:b3:f3:db | ip_address='169.254.192.3', subnet_id | ACTIVE | | | 124a61db46a24ebbadda7caa47de29a1 | | ='3af6b6be-972a-4fe5-bdc8-717a24a623a4' | | | d37fdab9-0490-47a4-a020-a3017c690c2a | HA port tenant | fa:16:3e:22:ca:96 | ip_address='169.254.192.4', subnet_id | ACTIVE | | | 124a61db46a24ebbadda7caa47de29a1 | | ='3af6b6be-972a-4fe5-bdc8-717a24a623a4' | | | e6688ece-5936-42bf-affa-028b182f9bf4 | | fa:16:3e:c1:a4:15 | ip_address='10.0.0.101', subnet_id='25b22b42 | DOWN | | | | | -4b8b-44bc-a0fc-cc512a189d4d' | | +--------------------------------------+----------------------------------------------+-------------------+------------------------------------------------+--------+ Errors in neutron server log about the gateway port creation (e6688ece-5936-42bf-affa-028b182f9bf4): /var/log/neutron/server.log:2017-05-14 12:32:49.159 127313 INFO neutron.plugins.ml2.plugin [req-15df71a6-ee71-4fe3-90ea-be5b98790b1c - - - - -] Attempt 2 to bind port e6688ece-5936-42bf-affa-028b182f9bf4 /var/log/neutron/server.log:2017-05-14 12:32:53.521 127311 WARNING neutron.plugins.ml2.rpc [req-2956d1a9-251b-4180-8b83-293380d01ce9 - - - - -] Device e6688ece-5936-42bf-affa-028b182f9bf4 requested by agent ovs-agent-overcloud-controller-1.localdomain on network 35f15b00-62ec-4d2d-a033-6cb607c87f59 not bound, vif_type: ovs /var/log/neutron/server.log:2017-05-14 12:32:58.104 127311 WARNING neutron.plugins.ml2.rpc [req-480a99ee-60f5-498e-b550-735a452a5f05 - - - - -] Device e6688ece-5936-42bf-affa-028b182f9bf4 requested by agent ovs-agent-overcloud-controller-2.localdomain on network 35f15b00-62ec-4d2d-a033-6cb607c87f59 not bound, vif_type: ovs /var/log/neutron/server.log:2017-05-14 14:00:30.112 127311 WARNING neutron.plugins.ml2.rpc [req-7bae8287-d772-41f5-b657-e71318045e6e - - - - -] Device e6688ece-5936-42bf-affa-028b182f9bf4 requested by agent ovs-agent-overcloud-controller-0.localdomain on network 35f15b00-62ec-4d2d-a033-6cb607c87f59 not bound, vif_type: ovs
