I am facing a problem with nova-network. I have configured bridge networking and I have set my IP as static but whenever I restart nova-network the IP of my bridge br100 changes from to

And sometimes I see the IP itself changes to when I launch an instance. I have installed Openstack Essex on Ubuntu 12.04. Right now I am trying to do a single node installation. So both my nova-compute and nova-network are on same node. My /etc/network/interface file is as follows:

auto lo iface lo inet loopback

auto eth0 iface eth0 inet static address netmask broadcast gateway

auto br100 iface br100 inet static bridge_ports eth0 bridge_stp off bridge_maxwait 0 bridge_fd 0 address netmask broadcast gateway I am having a hard time because of this IP change. Kindly provide a solution.

Thanks, Neha Rawat

See if this helps.

Follow the same and see the configuration inside nova.conf
