hello, I am completely new to openstack. I am having a few doubts regarding openstack. Googling about it didn't help me. I am doing a project on implementing a private cloud using Openstack. My final goal is that I should be able to run openstack on two systems, one acting as a server and the other as a client. The client should be able to access the instances which are created in the other system's horizon. I have managed to install openstack on both the systems. I don't understand what are controller and compute nodes. Should both these nodes be installed on the same system?

  • how can access the instances created on one system from the other? (Both are connected using ethernet cable)
  • is the LAN connection necessary or is there some way to access the instances from anywhere?

    Please excuse me if I sound dumb. Please kindly help me guys.

Please reformulate the question, it is a little bit confused. Basically you have two different Openstack instances, and you want access to Horizon OS1 from a VM spawned on OS2. Is that correct?

@Antonio G. Thank you for your reply. I am basically having two systems, each having openstack installed on ubuntu. Now I have connected both of them using ethernet cable. Now what I want is accessing the instances created in one system from the other.

OK, in this case you have to describe the networking you are using, or at least post the configuration inputs you used in order to install OS (answer files in case of packstack). Have you tried assigning Floating IPs to VMs and then trying a ping between them?

@Antonio G. I haven't tried assigning floating IPs. I didn't get your first part. I haven't used any networking. I have just run ./stack.sh on both systems. I have just connected them using ethernet cable. Could you please explain how to do that? I am very new to openstack and cloud.

I think what u have done is installed devstack on both the systems. One devstack installation is sufficient. It has everything controller, compute and network node. Now what u can do is assign a floating ip to a VM that is recognizable in your private network and then try to ping the VM from the other system. Then u can run the webserver on that VM and try the use cases.

@sanghai. Yes I have installed devstack on both the systems. My doubt is should we connect both of them using LAN cable or is there a way to access that IP anywere? and also could you please tell me how to assign floating IPs and how to access them through another system?

have you installed the devstack in a VM? Please describe your current system, if possible post the screenshots or link to them. I think then only i will be able to suggest the proper solution. I also think that you need to understand what openstack is and what it does. Please go through some videos
