2020-06-18 08:08:35 -0500 | commented answer | VM instance cannot be pinged or SSH I used the console to login to ubuntu and then change the IP of ens3 in the VM to match that of the IP provided and I am able to ping. But had no internet connection so had to add the gateway manually. But I can't see any bridge interface created on the controller. |
2020-06-18 04:10:38 -0500 | answered a question | VM instance cannot be pinged or SSH UPDATE 2: I saw some issues within the console.log of both instances. In the new VM the allocated IP and the console.log IP doesn't match. Old VM working (ping and SSH) : IP : 192.168.20.107 Console.log: 2)New VM: IP Address: 192.168.20.109 (more) |
2020-06-18 03:50:40 -0500 | commented question | VM instance cannot be pinged or SSH No I don't have any external dhcp server for provider network. My setup has 1 controller and 2 compute nodes. RabbitMQ is installed on controller. |

2020-06-17 10:07:48 -0500 | asked a question | VM instance cannot be pinged or SSH I have used a provider network based on the tutorial setup for Rocky Installation. I have 2 VMs fully working where I can ping them and also SSH into them using the keypair. When I try creating my third VM, the instance gets an IP but I am unable to ping. When I keep on deleting an creating new instances, sometimes I am able to ping the new instance but still unable to ssh. I get connection refused error. When I looked into the IPtables of the compute node I see that the new entries are not added when I create an instance. If it gets added I am able to ping the VM but still cannot SSH. The current setup is using DHCP I assume: https://imgur.com/0zTswHZ The ports are also created: https://imgur.com/vr8ry3A instance creation : openstack server create --flavor mi.large --image ubuntuServer --nic net-id=111fd1bd-b3bb-4085-8022-d1354c7d016f --security-group default --key-name n1 n1 Could anyone please provide an idea as to what is happening? Update: I am still able to create the instance without any error. But when I checked the logs I found it had 2 errors:

2019-06-14 11:54:18 -0500 | commented question | What activities create queues in RabbitMQ of openstack? @Bernd Bausch: I have actually read the link you posted up and down. And that is the basis of my understanding. However, I couldn't find any documentation which explains the sort of activities that triggers the usage of RabbitMQ exchanges, queues or connections. |
2019-06-14 11:39:46 -0500 | commented question | What activities create queues in RabbitMQ of openstack? I have been experimenting a lot with this. While the creation of an instance creates 1 exchange and 1 queue and 2 connection, it is never the same. I ran a script to keep creating instances until the resources exhaust. But it created few connections, exchanges and queues and then used the same. |
2019-06-11 05:59:49 -0500 | asked a question | What activities create queues in RabbitMQ of openstack? I have been trying to understand how RabbitMQ works and what creates exchanges and queues in RabbitMQ? I have gone through the openstack documentation and only an abstract info is provided. Could anyone point me in the direction of what creates exchanges and queues in RabbitMQ openstack? For instance, creating an instance normally creates a queue. When u repeat the creation of another instance, the previous queue that was created was being used. I was able to monitor this through enabling the management plugin of RabbitMQ and having access to the web management panel. |

2019-03-25 04:05:04 -0500 | asked a question | Rabbitmq message queue 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? |

2018-12-01 06:49:00 -0500 | commented question | Instance launch error. 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. |

2018-11-28 10:21:34 -0500 | commented answer | Instance launch error. 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...)) ?? |
2018-11-28 10:19:30 -0500 | commented answer | Instance launch error. 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. |
2018-11-27 06:15:37 -0500 | commented answer | Instance launch error. 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. |
