Talk:Xen Project Beginners Guide

Is the Guide Ready?

--Lars.kurth 15:44, 6 December 2011 (UTC) Hey Joseph, thanks for doing all this work. Let me know when you feel comfortable enough to publish the page on Category:Beginners. I was thinking of creating a new trailbox or including it into one of the existing ones at the top of the category.

--JosephGlanville Hi Lars, thanks for the props and apologies it has taken me so long to get back to this. Very busy at this stage in time. I will polish the guide off over the Christmas break and we can push it through then. :)

HELP

Hi Guys, I am trying to follow the guide for a test installation but unfortunately the link provided to Debian OS is non functional. Im not so sure if i can download a random OS, so can you please double check or confirm if any version would suffice, thank you.

--JosephGlanville Hi, this has been fixed. Sorry for the confusion.

• --Lars.kurth 13:15, 8 June 2012 (UTC) Joseph, can you check out Xen_Overview for the missing bits as well as Category:Debian for links to Debian?

Xen Project Document Day is This Wednesday, July 30: Beginner's Guide needs [updating](Russ Pavlicek)

This is a reminder that next Wednesday, July 30, is Xen Project Document Day.

Xen Project Document Day is a day to help improve overall Xen Project documentation, particularly that of the Wiki.

This month, it would be great if we could include the incomplete bits needed for the Beginner's Guide, including at least one decent diagram and some of the missing information called out in the Architecture section:

http://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide

All the information you need to participate in Document Day is here:

http://wiki.xenproject.org/wiki/Xen_Document_Days

If you get a few moments in the next week, please take a look at the current TODO list to see other items which need attention:

http://wiki.xenproject.org/wiki/Xen_Document_Days/TODO

So please think about how you can help out. If you haven't requested to be made a Wiki editor, save time and do it now so you are ready to go on Document Day. Just fill out the form below:

http://xenproject.org/component/content/article/100-misc/145-request-to-be-made-a-wiki-editor.html

We hope to see you Wednesday in #xendocs!

--Rich.T. If somebody here can provide a pencil sketch of:

A brief look at Xen Project architecture

To understand how storage, networking and other resources are delivered to guest systems we need to quickly delve into how the different bits of the software interact.

... and link to it here; I will try to put together a professional-looking diagram using https://www.lucidchart.com/

Example: https://drive.google.com/file/d/0B_kSZeNQ1ivtV3phSVY5MHFqR2M/edit?usp=sharing

--Lars.kurth 09:31, 30 July 2014 (UTC) Not sure I fully buy into the missing pieces (except for the network piece)

We have Xen_Overview and Getting_Started which cover some of what you are looking for. Admittedly these can be improved - in particular in light of articles such as

• http://www.brendangregg.com/blog/2014-05-07/what-color-is-your-xen.html
• http://www.brendangregg.com/blog/2014-05-09/xen-feature-detection.html
• http://www.informit.com/articles/article.aspx?p=2233978

And the sources for some of the diagrams in these can be downloaded from http://www.slideshare.net/xen_com_mgr/xen-hypervisor-for-the-cloud-frontier-meetup

--Rich.T. So, would this do for the guide?

That should work, unless you find a better one Rcpavlicek 17:42, 30 July 2014 (UTC)

Proposed Changes

 DaveHill (talk) (talk) 21:50, 6 October 2018 (UTC) I'm not sure how carefully changes to the wiki are reviewed before finalizing. I've been working through the Xen Project Beginners Guide and would make some changes which I would propose here first for comment.

The first one would be to correct an error in the section below on setting up xenbridge.

This file is very simple. Each stanza represents a single interface. Breaking it down “auto eth0” means that eth0 will be configured when ifup -a is run (which is run a boot time) what this means is that the interface will automatically be started/stopped for you. “iface eth0” then describes the interface itself, in this case it merely specifies that it should be configured by DHCP - we are going to assume that you have DHCP running on your network for this guide. If you are using static addressing you probably know how to set that up. We are going to edit this file so it resembles such:

    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp
    
    auto xenbr0
    iface xenbr0 inet dhcp
        bridge_ports eth0

 DaveHill (talk) (talk) 21:50, 6 October 2018 (UTC):The eth0 lines in the file are

   auto eth0
   iface eth0 inet dhcp

but should be

   auto eth0
   iface eth0 inet manual

(as per the Important Note! here:https://wiki.xenproject.org/wiki/Network_Configuration_Examples_(Xen_4.1%2B) and my own experience).
