Hey guys, I'm working on an OpenStack setup and followed the basic 3 node installation example on Ubuntu 12.04 using the from http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom repository. I set up network with the recommended quantum-networking.sh. So far everything worked at first. Today I found that the external router-ip wasn't reachable anymore. So I rebootet the networking node and it became worse than before. So here is my status after reboot: root@network:~# ip a 1: lo: mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:50:56:9d:b1:67 brd ff:ff:ff:ff:ff:ff inet 192.168.0.232/24 brd 192.168.0.255 scope global eth0 inet6 fe80::250:56ff:fe9d:b167/64 scope link valid_lft forever preferred_lft forever 3: eth1: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:50:56:9d:e6:75 brd ff:ff:ff:ff:ff:ff inet 10.10.10.232/24 brd 10.10.10.255 scope global eth1 inet6 fe80::250:56ff:fe9d:e675/64 scope link valid_lft forever preferred_lft forever 4: eth2: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:50:56:9d:8c:95 brd ff:ff:ff:ff:ff:ff inet6 fe80::250:56ff:fe9d:8c95/64 scope link valid_lft forever preferred_lft forever 6: br-int: mtu 1500 qdisc noop state DOWN link/ether aa:7a:ae:66:32:46 brd ff:ff:ff:ff:ff:ff 7: br-ex: mtu 1500 qdisc noop state DOWN link/ether 00:50:56:9d:8c:95 brd ff:ff:ff:ff:ff:ff 8: tap66178edc-18: mtu 1500 qdisc noop state DOWN link/ether c2:18:3b:96:24:f8 brd ff:ff:ff:ff:ff:ff inet 10.5.5.2/24 brd 10.5.5.255 scope global tap66178edc-18 9: qr-27a2e49b-d0: mtu 1500 qdisc noop state DOWN link/ether 8a:a3:c3:cc:71:8a brd ff:ff:ff:ff:ff:ff inet 10.5.5.1/24 brd 10.5.5.255 scope global qr-27a2e49b-d0 10: qg-9ba11a5d-c3: mtu 1500 qdisc noop state DOWN link/ether c6:d5:37:3a:e0:97 brd ff:ff:ff:ff:ff:ff inet 80.237.213.208/26 brd 80.237.213.255 scope global qg-9ba11a5d-c3 11: br-tun: mtu 1500 qdisc noop state DOWN link/ether 4e:68:12:ca:e8:42 brd ff:ff:ff:ff:ff:ff What I miss in the ip configuration is the external ip 80.237.213.232 on br-ex that had been there before reboot. root@network:~# ip r default via 192.168.0.225 dev eth0 metric 100 10.10.10.0/24 dev eth1 proto kernel scope link src 10.10.10.232 192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.232 No routes are set besides the one that are brought up by linux's network stack. In this case is 192.168.0.0/24 my management lan and 10.10.10.0/24 my data-lan. I use GRE tunnel to connect compute nodes to quantum. Please let me know if you need additional information. You'll find some output from quantum commands below. root@network:~# quantum net-list +--------------------------------------+----------+--------------------------------------+ | id | name | subnets | +--------------------------------------+----------+--------------------------------------+ | 09d13045-56c0-4747-9aa1-1ae04c98f230 | demo-net | 2eac3bbd-0547-49a3-9696-42b16a338ca9 | | f665454d-8159-4d13-a40f-d3d1f0bc1149 | ext_net | 133a7656-bdff-4814-8b6b-ecdf7b372973 | +--------------------------------------+----------+--------------------------------------+ root@network:~# quantum subnet-show 2eac3bbd-0547-49a3-9696-42b16a338ca9 +------------------+--------------------------------------------+ | Field | Value | +------------------+--------------------------------------------+ | allocation_pools | {"start": "10.5.5.2", "end": "10.5.5.254"} | | cidr | 10.5.5.0/24 | | dns_nameservers | 8.8.8.8 | | enable_dhcp | True | | gateway_ip | 10.5.5.1 | | host_routes | | | id | 2eac3bbd-0547-49a3-9696-42b16a338ca9 | | ip_version | 4 | | name | | | network_id | 09d13045-56c0-4747-9aa1-1ae04c98f230 | | tenant_id | cf4250b268194c4dbbd9c85ae8f1ceba | +------------------+--------------------------------------------+ root@network:~# quantum subnet-show 133a7656-bdff-4814-8b6b-ecdf7b372973 +------------------+------------------------------------------------------+ | Field | Value | +------------------+------------------------------------------------------+ | allocation_pools | {"start": "80.237.213.208", "end": "80.237.213.223"} | | cidr | 80.237.213.192/26 | | dns_nameservers | | | enable_dhcp | False | | gateway_ip | 80.237.213.193 | | host_routes | | | id | 133a7656-bdff-4814-8b6b-ecdf7b372973 | | ip_version | 4 | | name | | | network_id | f665454d-8159-4d13-a40f-d3d1f0bc1149 | | tenant_id | 09a14c7334094f86b75938978db58d99 | +------------------+------------------------------------------------------+ root@network:~# quantum router-list +--------------------------------------+-----------------+--------------------------------------------------------+ | id | name | external_gateway_info | +--------------------------------------+-----------------+--------------------------------------------------------+ | cc2cd248-ce60-47ff-841a-6cbf6915b86c | provider-router | {"network_id": "f665454d-8159-4d13-a40f-d3d1f0bc1149"} | +--------------------------------------+-----------------+--------------------------------------------------------+ root@network:~# quantum port-list -- --device_id cc2cd248-ce60-47ff-841a-6cbf6915b86c --device_owner network:router_gateway+--------------------------------------+------+-------------------+---------------------------------------------------------------------------------------+ | id | name | mac_address | fixed_ips | +--------------------------------------+------+-------------------+---------------------------------------------------------------------------------------+ | 9ba11a5d-c371-4560-8f6d-edeccc90d8ef | | fa:16:3e:3f:2d:3a | {"subnet_id": "133a7656-bdff-4814-8b6b-ecdf7b372973", "ip_address": "80.237.213.208"} | +--------------------------------------+------+-------------------+---------------------------------------------------------------------------------------+ Right now I don't know where to start debugging, so any help is appreciated.
