Zeeshan's questions

I am trying to configure Neutron without auth_strategy or keystone service but as I am a beginner to Openstack Neutron can't find the possible values for the mentioned configuration key.

I have ovn architecture running on the same node, just to be clear northbound DB and southbound DB, controller everything is running on the same node, now I think the problem can be

1. In my Architecture
2. or southbound DB configurations

Can you guys validate this architecture and Why I am getting output from northdb, but now southdb. attaching the outputs below

Scenario: We are trying to develop our Virtual Network using Open Virtual Network or OVN, We need our Virtual Network Switches running firstly on the root Virtual Router, and there are some other Virtual Switches as well. I was Working on the openvswitch and OVN but a lot of things are missing for me, and there are some unlinked dots between the deployment itself and there are some problems. My Question has 3 further Parts.

1. Is it possible at all to use Neutron as our Network Manager without OpenStack cloud installation?
2. Is it a good approach?
3. if not then are there any cookbooks available for OVN, I am not talking about man-pages.

Any help would be highly appreciated.

P.S. I am thinking about this because OVN got merged with Neutron, and it could be one of the possibilities.

I am trying to install OpenStack since days, on Centos7 with Stein distribution I am installing the Undercloud via triplo repository but two stages are failing with errors, they are given below:

1. Failed to Install python-gnocchiclient

/Stage[main]/Gnocchi::Client/Package[python-gnocchiclient]/ensure: change from 'purged' to 'present' failed: Execution of '/bin/yum -d 0 -e 0 -y install python-gnocchiclient' returned 1: Error: Nothing to do"

2. Failed to Install python-pankoclient

Stage[main]/Panko::Client/Package[python-pankoclient]/ensure: change from 'purged' to 'present' failed: Execution of '/bin/yum -d 0 -e 0 -y install python-pankoclient' returned 1: Error: Nothing to do"

I am new to Openstack, and Centos Maybe I am missing something don't have a clue even tried to install them Manually could not find any luck in that as well.

Can anybody explain What is going wrong here?

Update: I am also receiving this error on the yum install command

https://trunk.rdoproject.org/centos7/af/f5/aff5d8f30d73cf34e9a52a0b070143f128e37e79_57e4b623/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

Update: Found the Package installation links

1. python-gnocchiclient

sudo yum install -y https://cbs.centos.org/kojifiles/packages/python-gnocchiclient/7.0.4/1.el7/noarch/python2-gnocchiclient-7.0.4-1.el7.noarch.rpm

2. python-pankoclient

sudo yum install -y https://cbs.centos.org/kojifiles/packages/python-pankoclient/0.7.0/1.el7/noarch/python2-pankoclient-0.7.0-1.el7.noarch.rpm 

but I am wondering why dependencies of tripleo undercloud is breaking here if I have to manually install all of these things What is the use of this thing?

If No then

• how relevant repositories will be subscribed?
• Updates will be Performed
  

Details

• What I am trying to do?

  I am trying to create our personal OpenStack cloud and install one undercloud node in VirtualBox, and I have a server blade in which I want to provision My OverCloud Nodes p.s. All the requirements are fulfilled in the context of machine specifications

• Why Did I ask this Question?

  I am trying to deploy an undercloud node for days with the below-given configurations

   [DEFAULT]
   local_interface = enp0s8
   local_mtu = 1500
   local_ip = 192.168.0.105/24
   generate_service_certificate = true
   enable_ui = true
   undercloud_debug = true
  
   [ctlplane-subnet]
   cidr = 192.168.0.0/24
   gateway = 192.168.0.105
   dhcp_start = 192.168.0.120
   dhcp_end = 192.168.0.140
  

  So my question is if I don't use subscription-manager What will be the impact is this the main reason that I am getting errors for days. The last error which I had is for the task Output for sync deployment HostsEntryDeployment and the error which I am receiving is

     1) /usr/libexec/os-refresh-config/configure.d/55-heat-config: No 
        such file or directory
     2) jq: error: Could not open file /var/lib/heat- 
        config/deployed/aa6e0893-386f-4f09-9a77- 
        077275ea6198.notify.json: No such file or directory
  
  

Update

Just to resolve the first error I have to copy the file from 55-heat-config and then change add the execution mode to the permissions of the file. I am wondering a lot of things I had to do myself. So either the newer OpenStack is buggy or My centos7 has a lot of problems which is not possible just by looking at the nature of the problems I am facing.

I been trying to install openstack Undercloud but failed, there were different reassons but the last reason was, I am attaching Logfile here. I am a beginner could not find any help online. This is my undercloud.conf file is given below.

[DEFAULT]
local_ip = 192.168.0.105/24
undercloud_public_vip = 192.168.0.110
undercloud_admin_vip = 192.168.0.111
local_interface = enp0s3
masquerade_network = 192.168.0.0/24
dhcp_start = 192.168.0.100
dhcp_end = 192.168.0.150
network_cidr = 192.168.0.0/24
network_gateway = 192.168.0.105
inspection_iprange = 192.168.0.160,192.168.0.199

Json file is generated dynamically so the root of the problem must be
