Say, you have two nic on the host: eth0(public network) and eth1(private network), and you use FlatDHCP for network configuration. All the instances are in the private subnet. Then you should just add networks like: nova-manage network create demonet 10.0.0.0/24 1 256 --bridge=demonetbr1 --bridge_interface=eth1 When nova create instances, a bridge called 'demoethbr1' is created and a dhcp server is bind on it. The outbound network traffic of instances go out via eth0(public network) of the host. 2012/8/23 Xin Zhao <xzhao at bnl.gov> > Hello, > > I follow the instruction below to install openstack on RHEL6, but it only > shows how to configure network with one NIC. > Where can I find the doc about configuring openstack network with both > public facing and private facing NICs, on RHEL6? > > http://docs.openstack.org/**essex/openstack-compute/** > install/yum/content/compute-**configuring-guest-network.html<http://docs.openstack.org/essex/openstack-compute/install/yum/content/compute-configuring-guest-network.html> > > By the way, the official doc in the above link is for ubuntu.
