Open Stack

Silvia-


1)      Not totally sure what you’re asking.  When `devstack’ completes there should be an instance of Horizon running on that machine.  You can then connect to that Horizon from any other machine on that network, assuming your host has a routable IP address (using 127.0.0.1 as the HOST_IP would make Horizon only available from that machine).  Note, by default Horizon listens on port 9000 so make sure you are trying to connect to 10.1.115.126:9000

2)      Yes, currently the host information is stored in the DB but there is a lot of work going on in that area.  We hope to move to an object model where the compute nodes will be sending state information directly to the scheduler in the Kilo release.

I’d be curious to know what it is about the scheduler that you are planning on working on.  I should also point out that we have a weekly IRC meeting to discuss scheduler issues at 1500 UTC at #openstack-meeting (the meeting is titled Gantt which is the name of the new scheduler project we are creating), you’re welcome to join if that time zone works for you.

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
