Hi Friends

I am using Grizzly Version on CENTOS 6.3. When I am trying to start openstack-nova-network service on Cloud Controller Node but it gives me error "openstack-nova-network dead but pid file exists". In between, i had stop the iptables services and selinux to off. For more information email me vicky_3k2000@yahoo.com . Here I am paste my contents of nova.conf file and logs of /var/log/nova/network.log

nova.conf

COMPUTE/APIS: i you have separate configs for separate services

this lag is required for both nova-api and nova-compute
