Open Stack

Hi All

 

I try to install openstack on multi-node . 

I can boot instance and use vnc console to visit the instance .

But , I cannot access outside in instance .

 

I found the fixed ip range didn’t put on the br100 at compute-node only on
compute-controller. The compute-node only install nova-compute

On compute-node , ip addr

1: lo: <LOOPBACK,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master
br100 state UP qlen 1000

    link/ether 00:0c:29:cf:ec:d7 brd ff:ff:ff:ff:ff:ff

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state
UP qlen 1000

    link/ether 00:0c:29:cf:ec:e1 brd ff:ff:ff:ff:ff:ff

    inet 192.168.7.153/27 brd 192.168.7.159 scope global eth1

    inet6 fe80::20c:29ff:fecf:ece1/64 scope link 

       valid_lft forever preferred_lft forever

4: br100: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 

    link/ether 00:0c:29:cf:ec:d7 brd ff:ff:ff:ff:ff:ff

    inet6 fe80::20c:29ff:fecf:ecd7/64 scope link 

       valid_lft forever preferred_lft forever

 

on compute-controller :

1: lo: <LOOPBACK,UP,LOWER_UP> 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

    inet 169.254.169.254/32 scope link lo

    inet6 ::1/128 scope host 

       valid_lft forever preferred_lft forever

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master
br100 state UP qlen 1000

    link/ether 00:0c:29:88:31:51 brd ff:ff:ff:ff:ff:ff

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state
UP qlen 1000

    link/ether 00:0c:29:88:31:5b brd ff:ff:ff:ff:ff:ff

    inet 192.168.7.151/27 brd 192.168.7.159 scope global eth1

    inet6 fe80::20c:29ff:fe88:315b/64 scope link 

       valid_lft forever preferred_lft forever

4: br100: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 

    link/ether 00:0c:29:88:31:51 brd ff:ff:ff:ff:ff:ff

    inet 10.0.0.3/27 brd 10.0.0.31 scope global br100

    inet 192.168.4.33/27 brd 192.168.4.63 scope global br100

    inet6 fe80::20c:29ff:fe88:3151/64 scope link 

       valid_lft forever preferred_lft forever

 

could Any one tell me why ? Or tell me how openstack set network bridge on
compute-node so that I can figure out what happened .
