Hi all, I installed neutron + ML2 with the latest version of devstack on Ubuntu 12.04.3 LTS.
After installation I launched an instance of cirros image. It seems that the
vm is assigned a
fixed ip correctly. (see below)
/=== network info ===/
/if-info: lo,up,127.0.0.1,8,::1/
/if-info: eth0,up,10.0.0.3,24,fe80::f816:3eff:fe45:4077/
/ip-route:default via 10.0.0.1 dev eth0/
/ip-route:10.0.0.0/24 dev eth0 src 10.0.0.3/
The problem is I can ping 10.0.0.1~10.0.0.3 and 192.168.8.170, but I can't ping
the other
IPs in 192.168.8.0/24, including public gateway(192.168.8.254).
Did I missed any settings in localrc?
I'm also confused why br-ex was assigned the public gateway IP, I thought it
would be the
HOST_IP.
I found these codes in lib/neutron:
/ EXT_GW_IP=$(neutron subnet-create --ip_version 4
${Q_FLOATING_ALLOCATION_POOL:+--allocation-pool $Q_FLOATING_ALLOCATION_POOL} --
gateway $PUBLIC_NETWORK_GATEWAY --name $PUBLIC_SUBNET_NAME $EXT_NET_ID
$FLOATING_RANGE -- --enable_dhcp=False | grep 'gateway_ip' | get_field 2)/
/ neutron router-gateway-set $ROUTER_ID $EXT_NET_ID/
/ if is_service_enabled q-l3; then/
/ # logic is specific to using the l3-agent for l3/
/ if is_neutron_ovs_base_plugin && [[ "$Q_USE_NAMESPACE" = "True"
]]; then/
/ CIDR_LEN=${FLOATING_RANGE#*/}/
/ sudo ip addr add $EXT_GW_IP/$CIDR_LEN dev $PUBLIC_BRIDGE/
/ sudo ip link set $PUBLIC_BRIDGE up/
/ ROUTER_GW_IP=`neutron port-list -c fixed_ips -c device_owner |
grep
router_gateway | awk -F '"' '{ print $8; }'`/
/ sudo route add -net $FIXED_RANGE gw $ROUTER_GW_IP/
/ fi/
/ if [[ "$Q_USE_NAMESPACE" == "False" ]]; then/
/ # Explicitly set router id in l3 agent configuration/
/ iniset $Q_L3_CONF_FILE DEFAULT router_id $ROUTER_ID/
/ fi/
/ fi/
Can anyone explain this?
Any help will be appreciated.
Here is my localrc:
