Open Stack

Duh, I must have been asleep when I wrote that.  The meeting is on Tuesdays, look for Gantt on the OpenStack meetings page:

                https://wiki.openstack.org/wiki/Meetings


1)      It all depends upon how routable the IP address is for the host running Horizon.  Since 10.x.x.x is not routable and only visible from other nodes on the 10.x.x.x network then moving from the office to your home you probably won’t be able to see it without setting up some sort of tunnel so that you can get to your Horizon machine from the outside.  Talk to your network people about how to get a routable IP address.

2)      Your best option would be to look at the code.  Check out the main filter scheduler in the current Nova source tree at:
nova/scheduler/filter_scheduler.py
                and then look at one of the filters such as:
                                nova/scheduler/filters/ram_filter.py

If you look at the tracking page for the priority work for Nova for the Kilo release at:

https://etherpad.openstack.org/p/kilo-nova-priorities-tracking

There’s a large section on the scheduler, you can follow the blueprints in that sections to see what work we are doing for the next release.

1- I'm asking what happens if I move my laptop from my office network to another one (e.g. if I need to use the dashboard also from home).
2- Have you got a code flow to better understand the information publishing process? And how it will be managed in the future?

I started my internship just one week ago, they told my that the purpose is add a feature that will consider also the network link status togheter with the host status. So I think that the scheduler should interact also with the network module, but by now I'm still lost in understanding the architecture and the OpenSTack scenario.

I think I will join the meeting when I have time, on which day is it?

Thank you again

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<http://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
