Hi All When I setting neutron for openstack network, I got some problem and doesn't know why.
I reference"Neutron Networking with Open vSwitch and Provider Networks <http://docs.openstack.org/developer/devstack/guides/neutron.html#disabling-next-generation-firewall-tools>" to setting my openstack network. Control node is work fine and NIC eth0 IP address can assign to br-ex successful Compute node NIC eth0 assign to br-ex failed ,and Compute all API service can't connect to Control My compute node local.conf in below ================ start ================ ubuntu@pismo-192-168-1-98:~/OpenStack/devstack$ more local.conf [[local|localrc]] ADMIN_PASSWORD=admin DATABASE_PASSWORD=admin RABBIT_PASSWORD=admin SERVICE_PASSWORD=admin SERVICE_TOKEN=admin DEST=/opt/stack LOGFILE=/opt/stack/logs/stack.sh.log VERBOSE=True LOG_COLOR=True SCREEN_LOGDIR=/opt/stack/logs MULTI_HOST=True DATABASE_TYPE=mysql HOST_IP=192.168.1.98 FLAT_INTERFACE=eth1 FIXED_RANGE=10.0.0.0/24 FIXED_NETWORK_SIZE=256 FLOATING_RANGE=192.168.1.0/24 Q_FLOATING_ALLOCATION_POOL=start=192.168.1.221,end=192.168.1.230 SERVICE_HOST=192.168.1.130 MYSQL_HOST=192.168.1.130 RABBIT_HOST=192.168.1.130 GLANCE_HOSTPORT=192.168.1.130:9292 ENABLED_SERVICES=n-cpu,rabbit,q-agt ## Open vSwitch provider networking options PHYSICAL_NETWORK=default OVS_PHYSICAL_BRIDGE=br-ex PUBLIC_INTERFACE=eth0 Q_USE_PROVIDER_NETWORKING=True Q_L3_ENABLED=False ================ end ================ My compute node NIC info in below ================ start ================ ubuntu@pismo-192-168-1-98:~/OpenStack/devstack$ ifconfig br-ex Link encap:Ethernet HWaddr 30:0e:d5:c7:59:3e inet6 addr: fe80::1cde:14ff:fed6:1fa1/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:289 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18096 (18.0 KB) TX bytes:648 (648.0 B) br-int Link encap:Ethernet HWaddr 46:6b:f2:e5:c9:41 inet6 addr: fe80::b801:4cff:feb6:cbc2/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:648 (648.0 B) br-tun Link encap:Ethernet HWaddr 36:0f:ae:d8:c6:43 inet6 addr: fe80::f4e4:b9ff:feab:5d1d/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:648 (648.0 B) eth0 Link encap:Ethernet HWaddr 30:0e:d5:c7:59:3e inet addr:192.168.1.98 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::320e:d5ff:fec7:593e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:40871 errors:0 dropped:0 overruns:0 frame:0 TX packets:28210 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7796067 (7.7 MB) TX bytes:5086230 (5.0 MB) Interrupt:109 eth1 Link encap:Ethernet HWaddr 30:0e:d5:c7:59:3f inet addr:10.0.0.98 Bcast:10.0.0.255 Mask:255.255.255.0 inet6 addr: fe80::320e:d5ff:fec7:593f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2538 errors:0 dropped:0 overruns:0 frame:0 TX packets:3135 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:189631 (189.6 KB) TX bytes:531277 (531.2 KB) Interrupt:112 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:3960 errors:0 dropped:0 overruns:0 frame:0 TX packets:3960 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:346996 (346.9 KB) TX bytes:346996 (346.9 KB) ================ end ================ The question are 1.In Open vSwitch provider networking options PHYSICAL_NETWORK=default <-- Is mean it use my NIC or my public network ? 2.PUBLIC_INTERFACE is same with FLAT_INTERFACE? 3.Why the SERVICE_HOST connect failed? I can ping or connect to SERVICE_HOST via other server,but compute node can't. 4.My compute node br-ex doesn't be assign eth0's IP,so it can't go out ? If yes,how to fix it ? Best Regards, Jau
