"node" is the baremetal node, correct. You don't install "some configuration" on it, you copy a full system image to it.

The node has to be undeployed because it is being used for an instance. You can't just put a new system on it without removing the previous system.

2019-09-20 01:19:52 -0500 commented question difference between instances vs virtual machines in used_now

There is no such thing as "virtual machine" in OpenStack. Instances are created using VMs, or containers, or baremetal. In other words, a VM can be a means of implementation, but strictly speaking it's not an OpenStack object.

2019-09-20 01:19:08 -0500 commented question difference between instances vs virtual machines in used_now

I suggest you ask this on the distribution list. Put [nova] (with the square brackets) in the subject.

2019-09-20 00:27:53 -0500 commented question difference between instances vs virtual machines in used_now

This is very strange and looks like a documentation bug to me.

2019-09-20 00:26:58 -0500 answered a question What's the meaning of `re-deploy` in the bifrost?

In Ironic terminology, "deploy" means creating an instance on a baremetal node. To use the node for another instance, it has to be undeployed (i.e. old instance is removed), then deployed once more.

I am not sure if you can interrupt the deployment process, but the last paragraph in your question is definitely correct.

2019-09-19 21:50:38 -0500 commented question [Linuxbridge] How to set up instances with layer-3 (external) networking?

There are many moving parts, and therefore other potential problems. For example, the router that connects instances to the external network must have SNAT enabled. Or something is wrong with the tunnel through which instance traffic flows. Let's however first ensure physical connectivity.

2019-09-19 21:45:45 -0500 commented question [Linuxbridge] How to set up instances with layer-3 (external) networking?

You say that your OS nodes can reach the internet. However they may use eth0 to do that. Can they reach the internet via eth1, which implements the external network in your cloud?

What I mean: virbr1, to which eth1 is connected, must have connectivity to the internet.

2019-09-19 21:37:24 -0500 commented question [Linuxbridge] How to set up instances with layer-3 (external) networking?

You can only insert NICs into bridges if the operating system knows these NICs. Consequently you can't insert the host PC's NICs into the OS nodes' bridges, because the operating system that runs on the OS nodes is not aware of those NICs.

2019-09-19 18:48:27 -0500 commented question Which openstack version is supported to use the openvswitch v2.9.2?

It seems you can configure yum to exclude packages, though I have never tried it. A search for yum excludeyields a few promising web pages such as https://www.tecmint.com/yum-lock-disa....

2019-09-19 17:38:34 -0500 commented answer Evey time I create a heat stack a new project is created what happens if I delete that project?

A project doesn't get resources reserved. It can obtain resources up to the quota limit. You don't lose anything (except a few database records) by creating projects.

2019-09-19 04:53:19 -0500 commented question Is it must install the ironic before install bifrost?

From the install guide:

The playbook will install and configure ironic

It looks like you only install Bifrost. It does the rest.

2019-09-19 02:14:17 -0500 commented answer Vm ping gateway DUP

I am confused. I thought the problem was solved.

I can only recommend you to check similar problems. I found two on ask.openstack.org and quite a few more on the internet at large. See my comments to the question.

If you need help, ask a specific question.

2019-09-19 02:11:18 -0500 answered a question What does The time-to-live in sec of idle connections in the pool mean?

It's a message queue timeout.

A message queue connection that is idle for 20 minutes is closed automatically. It looks like the parameter was introduced in Newton. It's used here: https://opendev.org/openstack/oslo.me... (look for ttl or item_ttl).

2019-09-18 18:59:55 -0500 commented answer Evey time I create a heat stack a new project is created what happens if I delete that project?

Resources are owned by projects. Therefore, by definition, foreign projects can't consume your resources and use up your quota. You are fine.

2019-09-18 18:55:29 -0500 commented question [Linuxbridge] How to set up instances with layer-3 (external) networking?

The absence of an IP address puzzled me as well initially. It turns out that eth1 is plugged into a bridge. The router's network namespace contains an interface that is also plugged into the bridge, and the router's gateway address as well as any floating IPs are set on that interface.

2019-09-18 17:09:32 -0500 commented question [Linuxbridge] How to set up instances with layer-3 (external) networking?

A dedicated network node is not needed. It's useful when the controller is overloaded.

2019-09-18 17:08:15 -0500 commented question [Linuxbridge] How to set up instances with layer-3 (external) networking?

To understand how instances are connected, study https://docs.openstack.org/neutron/la...

2019-09-18 10:26:21 -0500 commented question Which openstack version is supported to use the openvswitch v2.9.2?

Strictly speaking, therefore, it is not Neutron but the Neutron package on your OS (RHEL, Centos, OpenSUSE?) that automatically installs version 2.11 of openvswitch. i suggest you configure your package management system not to do that, install version 2.9.2 and try it out.

2019-09-18 10:23:19 -0500 commented question Which openstack version is supported to use the openvswitch v2.9.2?

There is an old spec, which was implemented some five years ago, for not checking Openvswitch versions anymore. This means that Neutron doesn't know which version is required.

2019-09-18 10:12:21 -0500 answered a question Evey time I create a heat stack a new project is created what happens if I delete that project?

See https://ask.openstack.org/en/question.... One never stops learning.

If you have no WaitConditions or SoftwareDeployments, it may be OK to delete the project, but I don't see a need for it.

2019-09-18 06:24:49 -0500 commented answer What's the `devstack` directory function in Ironic?

I don't know whether that's possible.

Either go through the code or just use the documentation. Developer docs include devstack setup instructions.

2019-09-18 02:31:41 -0500 commented question kolla ansible | not able to connect external network

Sorry I dropped the ball. So, there is connectivity from the router's network namespace to floating IPs, but not otherwise? This is strange and I don't have an answer. I would start with a thorough analysis of all network components in that namespace, including routing and netfilter.

2019-09-18 02:26:37 -0500 commented question Evey time I create a heat stack a new project is created what happens if I delete that project?

Which project is created? I am not aware of Heat creating projects, except if the template includes project creation.

2019-09-18 02:25:15 -0500 commented question [Errno 256] No more mirrors to try. while running packstack installation.

The software versions you are trying to install are almost three years old and not available on the normal Centos repos anymore. I suggest you use a more recent version.

Newest packages are puppet-openstack_extras-14.4.0-1.el7.noarch.rpm etc; your version is 9.

2019-09-18 02:07:03 -0500 answered a question What's the `devstack` directory function in Ironic?

You will find that many (or all?) OpenStack projects have a devstack directory. It contains the shell scripts and other files required to set up the project in a Devstack cloud. It's useful for example if you want to get a good understanding of the configuration parameters (see the settings file), or you want to understand how exactly the project is set up (start with the plugin.sh file).

2019-09-18 02:02:54 -0500 commented answer Vm ping gateway DUP

If this is an HA router, the instance should be reachable from two network namespaces on the nodes where the two redundant routers are located.

2019-09-18 02:01:26 -0500 commented answer Vm ping gateway DUP

I don't know if you are supposed to have connectivity from the network namespaces on other nodes. My guess: Only from compute nodes that run instances in the same network, perhaps also from controllers.

In any case, if you can access the Instances via floating IP, and you have DVR, all is fine.

2019-09-17 09:43:28 -0500 answered a question WARNING KVM acceleration not available, using 'qemu' ERROR

It means that the server on which you run the virt-install command is unable to use CPU virtualization extensions and is therefore emulating the CPU in software, using qemu.

This has nothing to do with OpenStack. It's also not an error but a warning, as the message says. The virtual machine will be rather slow but should be functional.

2019-09-17 09:40:20 -0500 commented answer Vm ping gateway DUP

What do you mean by "Can't connect VM get through qrouter"? What is qrouter, do you want to connect to a VM (from where) or from a VM (to where)?

2019-09-17 06:13:40 -0500 commented question Gnoochi not getting installed

Add the relevant part from your local.conf to your question. Also, there should be more expressive error messages; you may have to scroll up. Add those as well.

2019-09-17 06:11:27 -0500 commented answer Vm ping gateway DUP

It does belong in the [agent] section; see https://docs.openstack.org/neutron/la....

I fear you may have disabled DVR now, and your config works because of that. As admin, check router details to ensure it's DVR.

While Calico's documentation says that Pike and Queens have been used for development and mentions that Ubuntu 16.04 is known to work, you could give it a quick try with the Stein version of Devstack.
