Open Stack

I think:


1.       If you connect your laptop from another network, you need to connect to Horizon from another IP.

Horizon relays on the web server that is working on your laptop.



While I’m not very sure, but if you run command “keystone endpoint-list”, are those IPs for your endpoints “10.1.115.126” ?

In that case, your openstack would not work after the IP changed for your laptop.

If you connect to “the cloud” from your laptop only, then use “127.0.0.1” for everything should enough.

In local.conf, set:

    HOST_IP = 127.0.0.1



2.       Information for scheduler should from its message queue, “nova-compute” has periodic tasks send them.



Thanks.

Subject: [Openstack] Questions from a newbie

Hi,
I'm completely new in OpenStack's Universe and I need to understand a lot of things!
Bust let's start with a couple of questions.
1. I have installed OpenStack using DevStack in a physical machine (I have already an Ubuntu system). At the end of the installation there was written the address where I can open Horizon (e.g. 10.1.115.126). What happens if I connect my laptop from another network? Does it remain the same? Or should I do a specific configuration?
2. I will work with nova in particular, especially in the scheduling part. I would like to know where the scheduler take the information about the state of the host to assign it after the filter & weight.
I think that those parameters about the status of the host are memorised in the database, but it's only my hypotheses, I haven't read anything about it.
And if it's so, how are collected those information? By who?
Sorry if I did some silly question, but I would like to well understand the basis.
Let me also know if exist a good guide that explains how to start with OpenStack from zero!
Thank you
