Hi All,

Please help me , I need help urgently.

I have 3 Physical node Openstack Cluster. I have installed through All-in-one Packstack installer (Rocky). I have created Networks (Internal & External) , Routers and VMs (booting through Cirros), The problem is that my Openstack VMs network wont connect or ping to External Network (Physical LAN network where my controller node is.) Let me know if you need more information.

Help me by looking in my configurations.

I am doubting on my neutron configurations and bridging adaptors.

Please help asap.

How did you deploy the cloud? Can you describe your network configuration? Can you ping the router?

Thank you for prompt response.

I depolyed it via all-in-one setup which uses puppet, what files output you want to see. I cant ping router (if you are talking about openstack networks)

If you have three servers, it's hardly an all-in-one installation. Also, by default, Packstack doesn't connect the cloud's external network to your physical network. Without details of your non-default setup, it's very hard to say anything about the cause of the problem.

It would help to know what commands and answer files you used to set this up. It would also help if you described how you connected the cloud to the physical network.

A typical test is entering the DHCP namespace of the VMs' network and check connectivity to VMs' static IP addresses.

Ok, So here are the commands:-

yum install -y openstack-packstack packstack --allinone on main controller node

than I added compute nodes by separately.

I cant attach files here or paste output.
