I have 2 ubuntu node (controller and compute) that i installed openstack, module by module.
but i can not create any instance.
in nova compute logs show this error:
ERROR nova.compute.manager [req-42d9d648-b39f-4214-9e5e-b8fb8799c10e 91704884e43f48fcbd156b8d7429fc3e 5e055db0a5464dc1997ab0f456792271 - default default] Instance failed network setup after 1 attempt(s): keystoneauth1.exceptions.connection.ConnectFailure: Unable to establish connection to http://localhost:9696/v2.0/networks?id=163f0b54-e337-40ac-81af-958c24ceeb7f: HTTPConnectionPool(host='localhost', port=9696): Max retries exceeded with url: /v2.0/networks?id=163f0b54-e337-40ac-81af-958c24ceeb7f (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f4ce476a820>: Failed to establish a new connection: [Errno 111] ECONNREFUSED')

I installed Openstack in Ubuntu and started it using the ./start.sh command. When I try to login the dashboard, I get the error below about not being able to connect to Neuron:
ConnectionFailed at /project/
Connection to neutron failed: HTTPConnectionPool(host='192.168.204.173', port=9696): Max retries exceeded with url: /networking/v2.0/extensions (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f7efde4f460>: Failed to establish a new connection: [Errno 111] Connection refused'))
How do I fix this?
I have the following scenario:
server: Ubuntu 20.04.3 LTS
openstack installed with devstack
watcher 2.2.0
Every services seem to be working and i can see the watcher dashboard on localhost.
But I think I have an auth problem between watcher and keystone :
Error contacting Watcher server: Unable to establish connection
to http://x.x.x.x:9322/v1/services: HTTPConnectionPool(host='x.x.x.x', port=9322):

HTTP Connection object at 0x7fba33b1be50>: Failed to establish a new connection: [Errno 111] Connexion refusée')).
Attempt 6 of 6
I'm testing something on a VM, I put the same IP and the same password everywhere
Where should I look first ?
I am trying to integrate an Apache Atlas instance I have running with Apache Airflow. Once I set up the connection in airflow.cfg I tried running a DAG from the Airflow scheduler. I get the following error in the log.
[2021-02-02 20:50:47,958] {connectionpool.py:752} WARNING - Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f464b856950>: Failed to establish a new connection: [Errno 111] Connection refused')': /api/atlas/v2/types/typedefs

My airflow.cfg is configured as the following:
[lineage]
backend = airflow.lineage.backend.atlas.AtlasBackend
[atlas]
username = <username>
password = <password>
host = localhost
port = 21000
I have tried changing the host to http://localhost as well. I am not sure where to investigate in Atlas to identify why the connection is being refused.
Connection Refused means either service is not listening on the configured port or the wrong hostname.
Try to replace localhost to fqdn,
A good way to configure it correctly is to access atlas ui and simply put the hostname from the url to config.
I was able to solve the problem by adding the --hostname flag when starting the docker container for atlas. I then used the hostname I provided as the host in airflow.cfg
When I type the swift stat command, this error appears:
HTTPConnectionPool(host='controller', port=8080): Max retries exceeded with url: /v1/AUTH_d17698cf7bbf4dcc8fc59ed6f7b48052 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f1b0c2939a0>: Failed to establish a new connection: [Errno 111] Connection refused'))
And when I type this command to see if there's a listen on port 8080, nothing appears:
netstat -tanpu | grep ":8080"
and when I try to restart or start the swift service with service swift-proxy restart, an error appears:
Assertion failed on job for swift-proxy.service.
We have setup OpenStack using conjure-up on a (Ubuntu LTS server 16.04.3) single machine. All are services are up and running, and successfully I am able to upload images to the glance.
We wanted to save these glance images created by "glance image-create" in remote machine which have nfs server. So we have configured glance-api.conf file as below.
My glance-api.conf looks like this:
[glance_store]
filesystem_store_datadir = /var/lib/glance/images
default_store = file
And in glance controller node, I have mounted
remote machine Ip/home/glance/images/ in this directory path
/var/lib/glance/images
and have mentioned the same mounted directory path inside the glance-api.conf file.
I have created the two sample private network with some ip (192.168.1.0 and 10.221.50.0) but have not created a public network as at this moment I don't want to access this VM instance from outside.
When I am trying to launch the instance from dashboard UI as well as through CLI, I am getting below error.
Error: Failed to perform requested operation on instance "Ubuntu_Hawkbit", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].
Note: I have tried by associating Instance with different private network ,thinking that it may be network IP address issue but facing the same error.
When I check /var/log/nova/nova-compute.log logs, I see below error.
