I installed openstack-grizzly on ubuntu server 13.04 using https://github.com/ilearnstack/cloudgear This installation uses Linuxbridge. I created an internal network 192.168.0.0/24 . I am able to ping dhcp server which has the ip 192.168.0.3 but not the internal router 192.168.0.1. What am I missing here ? Below is the list of interfaces and bridges.

Is there any solution for this problem? I need it urgently

There is no interface for any router - I presume you added the a logical interface to the router for the internal subnet? Can you provide 'quantum port-list' and 'sudo ip netns'

I had a look at the script and it does not install the quantum-l3-agent which is needed to implement the router. So you will need to install and configure it yourself.

It also has use_namespaces=False - I recommend enabling namespaces if you also want to run a router on the same machine.

thanks for the reply. Do i have make any changes in the interfaces file? I am just using one nic. auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.35.141.91 netmask 255.255.255.0 gateway 10.35.141.1 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 10.35.141.1 this is the configuration of the interfaces file

Its worked now. Just one more thing. I am able to ping the router 192.168.0.1 but not the vm from the host machine. the vm ip is 192.168.0.2
