Xen Orchestra Lite

Marc.pezin

Xen Orchestra Lite is an ongoing project around XCP-ng and Xen Orchestra. it doesn't require you to host any virtual appliance and will allow you to do basic management of your host directly from the browser of your choice.

Pierre, the lead developer of the project wrote an extensive devblog on the project you can read here

This topic is dedicated to discussion ans questions around this project.

@marc-pezin Nice to see XO Lite (and XO 6) becoming reality . When and how will XO Lite be available for testing?

gskger

@marc-pezin After reading the blog post, one question / remark immediately comes up. To use XO Lite, the host must have a working internet connection to load the React JS app from your servers? Or is it just the computer that loads the app?

Silly me - the graphic says it all: it' only the computer.

Need internet access on your computer for now, not on the host

The script is loaded in your browser on your computer.

@gskger To answer about the availability: in fact, it's already working, but very very very basic for now. I'd like to have something "not ugly" to start, even with not a lot of features, so let's say end of this summer

But if you can't hold until then, it's pretty easy to test:

Create a /opt/xensource/www/xolite.html file
Put that inside:

<!DOCTYPE html>
<html lang="en" class="no-js">
  <head>
    <meta charset="utf-8" />
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1, shrink-to-fit=no"
    />
    <meta name="theme-color" content="#cc584c" />
    <title>XoLite</title>
  </head>
  <body>
    <noscript>You need to enable JavaScript to run this app.</noscript>
    <div id="root">The application is loading…</div>
    <script src="https://lite.xen-orchestra.com/dist/index.js"></script>
  </body>
</html>

Go in your host IP address <host address>/xolite.html

That's it!

edit: until the XAPI fix is in 8.2 or 8.3, consoles only work with Chrome.

@olivierlambert Is this still the standing method of testing XO Lite? It still works but seems to be pretty much at the same stage it was 1 year ago. I was hoping to see some of the new UI from the recent blog posts.

olivierlambert

We'll provide the new build soon from the same URL. The method will be a bit different too.

bogdantomasciuc

@olivierlambert Looking forward to it!

My test host has been reinstalled multiple times since I last looked at this so I just thought I would try it out again to see where things were at and it is completely broken for me.

By completely broken I mean:

Trying to install with

wget https://lite.xen-orchestra.com/dist/ -O /opt/xensource/www/xolite.html

Gives an HTTP 404 error.

Creating the xolite.html file as per above gets me an xolite login screen, but I cannot get past the login screen. Entering the root password and clicking on login does nothing. The login screen just sits there.

Hi @mjtbrady we are migrating the version from React to Vue.js and the deploy instruction is a bit different. @pdonias will come back to you with the right instructions

pdonias

Hi @mjtbrady, if you get the login screen, it means it's working. Are you sure you entered the right password for your host? You can check if there's been an error by opening the browser console with F12, then "Console" tab. If there's a SESSION_AUTHENTICATION_FAILED, it means you entered the wrong password (proper feedback on failed authentication will come soon ). If there's a different error message instead, could you post it here, please?

olivierlambert

wget https://lite.xen-orchestra.com/dist/ -O /opt/xensource/www/xolite.html

is now fixed

mjtbrady

@olivierlambert I confirm that the wget now works.

@pdonias I am sure the password was correct. It is a randomly generated one from my password manager. So it was cut and paste. But I just tried it again and is now working.

Thanks all.

pdonias

@mjtbrady Yes, there was an issue on our side but it's fixed, now. Thanks for the feedback and let us know if you have other issues

olivierlambert

Thank you @mjtbrady for the feedback

Thanks @pdonias for the fix

XO Lite can be cloned on the local computer or XCP-ng host, to run without internet?

mjtbrady

Looks good. I like that you have a dark mode in there form day one.

Just to manage my expectations.

Is the code that we are pulling "live" development, meaning that it is likely to change and potentially be broken frequently or is it "snapshots" where everything that has been implemented is supposed to work?

Or something else?

olivierlambert

Until it will be available at a version 1.0, it will be loaded from our server. This is easier to rebuild/distribute a new version until we are satisfied with the design/features.
We rebuild manually, so we won't rebuild when it's broken. Keep in mind this is light version of XO, so you won't have tons of features except basic stuff to bootstrap your infrastructure.
When we'll reach the production version, we'll package it inside XCP-ng directly, so no internet connection will be needed. We'll see how often we'll update it (and how). In an ideal world, a mechanism that's able to get a more recent version from our server if you can and fallback to the version installed would limit the frequency of package update, but we need to think carefully on how to do this.

Hi, @olivierlambert
Looks like lite version is perfect for start but looks like something is missing here?

where are the logs from webserver to troubleshoot this issue?
