What activities generally create the message in the queue for RabbitMQ? I have enables the management plugin to keep a tab on rabbitmq. Does activating TCP connections to a client create a message as well?

@Bernd Bausch : Any take on the issue ?

I am having issues setting up neutron.

Infrastructure details:

Operating System : Ubuntu 18.04.1 LTS

1 x controller and 1 x compute

Openstack installation : Rocky

Guide following:https://docs.openstack.org/install-guide/ (https://docs.openstack.org/install-gu...)

Each node has 2 NICs:-

NIC 1 (eth0) - https://imgur.com/a/7QbcU1E (gateway: 192.168.0.1)

NIC 2 (eth1) (Has internet connection) - https://imgur.com/a/tyddrjA (gateway: 192.168.10.1)

ifconfig output - https://imgur.com/a/tyddrjA

Openstack network : https://docs.openstack.org/install-guide/overview.html#networking-option-2-self-service-networks (https://docs.openstack.org/install-gu...) (Option2: Self-Service Network)

I have followed the instructions to the exact thing in the documentation few times.

Error while launching a new instance:

Error: Failed to perform requested operation on instance "node11", the instance has an error status: Please try again later [Error: Build of instance bb5703a2-2bfe-42a9-9e69-7bb1a8e8cfd5 aborted: Failed to allocate the network(s), not rescheduling.].

Closing this one, based on your inputs, I have started openstack installation from scratch and stuck at neutron config. I have created a new question with latest details of the configuration.

Should I be creating a bridge between the NICs before setting up neutron on the controller and compute. I am trying a fresh install again.

What I am trying to do is to get two clouds setup and their instances communicate with each other. I don't know what network type should I setup: Networking option 1 or networking option 2 mentioned here (https://docs.openstack.org/install-guide/overview.html (https://docs.openstack.org/install-gu...)) ??

In this explanation: https://docs.openstack.org/neutron/rocky/install/controller-install-option1-ubuntu.html (https://docs.openstack.org/neutron/ro...) The linux bridge is supposed to be :physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME . And according to my setup management interface = eth0 and provider interface = eth1.

1) None of these ports are listed in the response. But I have created all the services and their endpoints and I can access all of them on the browser.

2) Yes I have enough resources.

3) My hardware does support virtualization. But nonetheless I have kept virt_type to qemu.

@Bernd Bausch: Updated the post with details and all info about the network.

Thanks @Bernd Bausch: Yes I did update the original post, but I suppose it is awaiting moderation. This is the logs from neutron :https://pastebin.com/EY4tTRhJ

I have checked the config logs in the controller and compute nodes for nova and it is perfect.

I have added the nova compute log from one of the compute nodes. I can see a neutron error in there. Is that the problem?

Yes I did try without the volume and it gives me another error. Added to the original post. I will try to fix the volume setup though. But even without the volume it gives me error.

Its the default Cirros that I tried.

Setup Information: 1xController (name: controllerstack) 2xCompute nodes. (name: computestack, computestack2)

Network setup : NIC 1 (eth0) - 192.168.0.0/24 Network setup : NIC 2 (eth1) - 192.168.10.0/24 (has internet connection)

Setup guide being followed: Openstack Rocky Installation guide (https://docs.openstack.org/install-guide/ (https://docs.openstack.org/install-gu...))

I am trying to create an instance from horizon on the controller and I get the following error

Error: Failed to perform requested operation on instance "c3", the instance has an error status: Please try again later [Error: Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 05d7247e-c157-4744-82ba-8a73c5cb42ae.].

I haven't gone through the logs in each compute nodes. Any input would be valuable.

I was able to fix the issue. I had to restart the memcache service. I still keep getting the errors every now and then. And when I do :

1. service memcached restart.
2. Clear browser cookies and cache.

But it is sometimes still annoying even with the fix.

I am installing openstack using https://docs.openstack.org/install-guide/openstack-services.html (https://docs.openstack.org/install-gu...) (rocky)

I am stuck at neutron installation. I am using the https://docs.openstack.org/neutron/rocky/install/controller-install-option1-ubuntu.html (Networking Option 1: Provider networks). After all the steps and at the verification when I run : $ openstack extension list --network

I get the below error:

REQ: curl -g -i -X GET http://controllerstack:9696/v2.0/extensions -H "Accept: application/json" -H "User-Agent: openstacksdk/0.17.2 keystoneauth1/3.10.0 python-requests/2.18.4 CPython/2.7.15rc1" -H "X-Auth-Token: {SHA1}2e862b28c61bdb114ca81e4ace5c9723d4c25270"

Retrying in 0.5s.</urllib3.connection.httpconnection>

I don't know what is the issue. The name of my controller is controllerstack and I have the right ip address mentioned in /etc/hosts and furthermore, I have no spelling issues in nova.conf.
