2019-02-07 10:36:58 -0500 asked a question OpenStack and OpenDaylight Integration

Hello,

I want to integrate OpenStack (DevStack Pike) and ODL Berylium. And I am trying to follow-up the dozen tutorials that are one the internet. One is this: https://opensourceforu.com/2017/04/in...

The problem is that when you configure the elements for neutron, it says to shutdown neutron and I cannot do that. Moreover, if I make the modifications and then a reboot for the modifications to be active, the neutron will not start or even worse it does not work correctly, meaning that I am trying to login in OpenStack and if I want to access Network section, it won't show anything, because Neutron service is not working.

Please, I have tried all the tutorials on the internet and tried almost 10 times, can you tell me how to do this correctly and advance with my studies.

Thank you, Silviu

2018-12-05 13:57:24 -0500 asked a question floating IP problem: Host Unreachable

VirtualBox->VM with Ubuntu: 16.04.4 -> OpenStack Pike installed with DevStack 2 interfaces: - 1 interface bridged: 192.168.X.X subnet (wi-fi) - 1 interface NAT: 10.0.3.0/24 subnet -> host_ip specified when installed OpenStack is 10.0.3.15

I have configured: internal network external network, from admin in all the ways: using flat, local. I have used for the external network both of the subnets. I have the rules setup to let ping messages ingres.

Sill cannot access the Floating IP -> Destination Host Unreachable.

I have lost my hope. Please, can you help?

Thanks, Silviu

How did you setup the external network? What subnet did you use (the one from the bridge network or nat)? What gateway has the router assigned to the external network? Is the same with the gateway from the external network? I just need some guidance cause I don't know why is not working.

Can you help me with some steps? I have created once again everything, using flat, but still cannot access the floating IP. My bridge network (from wi-fi) is 192.168.1.0/24. NAT network is 10.0.3.0/24. I have tried with flat, using bot subnets, but nothing. Please, some advice or steps?

Thank you. I understand, but what was your config and how did you createthe external network: local, flat, vlan? Did you use NAT for the host in virtual box?

2018-12-04 17:49:38 -0500 asked a question Floating IP cannot be pinged

I have OpenStack Pike installed in a VM on a virtual box. The VM has one bridged interface for internet and another one with NAT and the IP from the NAT interface is used for OpenStack. After I have configured the compute instance with the internal and external network, router and floating IP -> I cannot access the floating IP. Please, what should I do, because I have tried different solutions and nothing works.

For example, when creating the external network I am using local, because flat is not working to be created, maybe because I don't now the name of the Physical net (is it ext-net?). Is it really necessary to use only bridge?

What should be the steps to work? What type of external network to create that works with the NAT set on my virtual box host (ubuntu 16.04.4) so that I can access the floating IP (the compute instance) from my host.

Thank you very much and hope you can help. Silviu

Hi Bernd.In virtual box I have created also a NAT interface and used that IP for OpenStack and it works.Now, I have another problem. Cannot access the compute instance with floating IP from the OpenStack host: Destination Unreachable? What should I do? It really works only with bridged mode? Thanks

Thank you very much Bernd. I am using an Ubuntu VM. When installed the Openstack used X.X.1.248 IP. Now, in another network, the VM has another IP. If I will setup the second interface with X.X.1.248, the dashboard should now open, right? I will test that and let you know. Thank you once again.

I am working with OpenStack for my PhD and I want to make a test environment using OpenStack to learn. I am using my laptop and the host IP from my laptop may vary due to the Network I am using. Is there any way to accommodate that or simply install it in a fixed place and that is it? Thank you.

2018-11-23 11:22:05 -0500 asked a question HOST_IP change in OpenStack Pike, cannot log into Dashboard

Hello. I have installed openstack pike on my local machine using devstack. I have downloaded Ubuntu 16.04 OS and then followed the procedure. Downloaded devstack, specified the necessary elements and HOST_IP in the local.conf and hit ./stack.sh. Everything worked.

Unfortunately now I am in another network and using another IP for the host. I have researched on google how to change IP, but nothing worked and I cannot log into the Openstack Dashboard. I have looked in keystone log and see that it still uses the old IP. I have changed the IP in the database, re-run ./stack.sh. Nothing works. Of course, I didn't found any resolution for OpenStack Pike. All the resolutions used rejoin-stack.sh, which is no longer present in my version.

Please, what are the steps that I need to use, for my OpenStack distribution, to be able to access the environment if I change network and implicitly the IP.

Thank you and I really hope that you can help me. Silviu
