I have been trying to install OPNFV os-odl_l2-sfc-noha scenario using FUEL installer. I have one Fuel-master, one control node and 1 compute node. I followed installation guidelines from

However I added public IP for interfaces in compute and control nodes since otherwise the network connectivity check failed.

When I install Openstack, it failes on both nodes with a lot of error messages starting with. Connection timed out - connect(2) at /etc/puppet/modules/osnailyfacter/manifests/fuelpkgs/setuprepositories.pp:21 on node fuel.

I'm stuck here, please guide me.

Lets clarify first which release are you using: Colorado (as in tag) or Brahmaputra to which documentation you referred? This task setup_repositories.pp will fail if can't reach repositories. So first of all it should be verified if you are able to connect external address (use dns name to check if resolving names is working) from failed node. In this case it probably failing because communication with external repositories is not possible through admin network, however in next phase of deployment this connectivity also needs to be possible through public network. Both of this cases can be verified through "Connectivity Check" in fuel web interface. I'm not sure what do you mean by "I added public IP for interfaces" - this should be done by fuel from ip address range which you defined in environment settings.

In case connection to external resources is forbidden in your local environment you can use local mirros from fuel master: - mirros addresses are different for different releases so please verify with appropriate documentation.

If you are using virtual machines and your admin network gateway is set to fuel master IP address please also ensure that on host machine where you run VMs you have these settings in /etc/sysctl.conf:

net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0

It will disable iptables rules on linux bridges used by VMs and is required for functional NAT through fuel master vm. You can check current value with cat /proc/sys/net/bridge/bridge-nf-call-iptables and if it set to 1 modify configuration as above and apply with sysctl -p

Hi, Thanks for your help!! I'm using Colorado release. I removed the manual IP's I gave for for the public interfaces and set the configuration in /etc/sysctl.conf and verified Connectivity check and it worked. But now Openstack installation is failing with this following error message Deployment has failed. All nodes are finished. Failed tasks: Task[cluster-vrouter/3] Stopping the deployment process!. When I checked the logs, it last try's to execute (Scope(Class[Osnailyfacter::Clustervrouter::Clustervrouter])) MODULAR: clustervrouter/clustervrouter.pp and it fails there.
