All:
I wanted to do the below using openstack (Icehouse). with the following
network connections on CenOS
I have two NICs on the machine and mine will be all in one installation.
one NIC (say NIC1) on my lab vLAN 192.168.5.x and second NIC not
configured on anything.
Now I wanted to have Openstack Installed on NIC1.
Assign an IP to second interface like (172.168.2.5)
And give that range in nova-network say like
nova network-create demo-net --bridge br100 --multi-host T
--fixed-range-v4 172.168.2.0/24
, Assign gateway as 172.168.2.1 ( I assume that openstack will create a
interface with that br100 with ip 172.168.2.1)
configure nova.conf like below:
openstack-config --set /etc/nova/nova.conf DEFAULT flat_network_bridge
br100
openstack-config --set /etc/nova/nova.conf DEFAULT flat_interface NIC2
openstack-config --set /etc/nova/nova.conf DEFAULT public_interface NIC2
Now my questions are :
Will i be able to create something like that?
I am able to do ssh and connect using private IPs as well, But my private
IP is not talking to outside world.
Can some body suggest? What is that I am doing wrong ?
Thanks
Dev
