Hi Anne,

I am using 3 servers all are having 4 lancard
node1 =
nova-api,nova-console,nova-compute,nova-manager,nova-volume,nova-cordinator.keystone.dashboard,mysql,rabbitmq,nova-network
eth0=10.83.18.208,eth1+eth2=172.24.31.1,eth3=172.24.30.1

node2 = nova-compute,nova-volume
eth0=10.83.18.209,eth1+eth2=172.24.31.2,eth3=172.24.30.2

node3 =  nova-compute,nova-volume
eth0=10.83.18.210,eth1+eth2=172.24.31.3,eth3=172.24.30.3

bridgeutils is installed on all nodes.



when i am creating nova network on node 1
nova-manage network create --fixed_range_v4=192.168.0.64/26
i am able to access the running vms from node1 and are getting ip in the
range of 192.168.0.66... and also able to access vms from external network
after assigning floating ips.

But when i am creating another network
nova-manage network create
--fixed_range_v4=192.168.0.128/26<http://192.168.0.64/26>
and after restarting nodes when i am launching the vms they are up and able
to get two ip
one in the first network and second from second network but i am not anle
to ping or access any instances, i am also able to attach floating ip to
access them from different machine other than node1, but no luck.
