XO Lite: building an embedded UI in XCP-ng

[Gheppy]

To be a good alternative to XCP-NG Center you have to do at least what XCP-NG Center does.
E.g:

• I haven't found in XOCE, so far, how to rearrange the VHDs of a VM, the only method, which I found , is to reattach them in the order I want,
• To be able to snopshoot,
• To be able to import and export,
• To be able to migrate a VM, implicitly to be able to add another host on which to migrate the VM. This is good when the current host has a problem,
• To group VMs by hosts, sometimes it is more useful to see which VMs are affected if you restart a host, XOCE displays them all but you cannot group/subgroup them on hosts that they are running on,
• It can be restarted even if it is the only host, XOCE only wants it if the VMs are all turned off.

In essence, XCP-NG Center does almost everything XOCE does, but manually. Which is OK when you have a breakdown.

Don't get me wrong I use XOCE the most and I understand its importance but sometimes a XCP-NG Center is good to have, especially a local one on the host.

i agree with @gheppy to have XCP-ng center run as a service on a sin out VM would be nice and with all the features of XOA instead of having to run XOA from sources to get all the features...you can run snapshots on a schedule with the center app and keep X number of iterations but are limited to local drive. instead of XO LITE why not go for xcp-ng center as a service with all options to run on a VM...i don know about most but i like the look and feel of xcp-ng center

@Gheppy it's a bit off topic but:

1. You can rearrange disk in Xen Orchestra, you can drag and drop them

I'm not sure to understand the rest, because that's precisely the goal of XO Lite, being able to get rid of XCP-ng Center to manage your pool, with equivalent features.

Did you missed the first post maybe? @dane7791 seems affected by the same problem. Please take time to read the first post with the link to the blog article. Everything is explained in there

Just a heads-up your certificate expired.

[olivierlambert]

Hi,

No the certificate is fine. The issue is on your side, from the XCP-ng version you have I assume (not fully up to date?)

@olivierlambert The command for wget specified in the initial post, will always re-download the xolite file. So can't be used in a crontab operation during the beta, in order to update the file locally.

However the following may be utilised as part of a crontab command section, line entry.

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

The additional option I added to the post here, will cause wget to check if the remote file to be downloaded has changed at all. Then only download the file if the remote has changed, otherwise will not. That will therefore as a result save a lot of bandwidth, for Vates when downloading the html file, if the check and download isn't too often!

So when this item has been validated, and if Vates agrees and allows can the original post be updated with the new wget specified here please?

Also the crontab entry and your downloaded xolite html will also need to be removed, once the XO Lite fully gets, rolled out as part of an updated XCP-ng. This in my opinion will have the likely hood of happening, during one of the 8.2 point releases as long as it fits the LTS rules, more likely though will be in 8.3 or later, and while in the next LTS release series.

@olivierlambert @clemencebx What vocabulary will be used when there's at least two layers (levels) of priority? Think of how old legacy bios system boards, handled the IDE physical drive boot priority connections! As well as documented in the manuals, for said items.

Hi,
Great work so far!
My suggestion is to have xo.little as little as possible, so:

1. create/add storage(iso) is a must to have
2. create/add network is a must to have
3. create/add VM is must to have
   all other things can be done after installing XO
   It was a challenge to configure a lab env. from scratch without WindowsPC so xo.lite is a good direction

[konsultaner]

@olivierlambert how can one contribute to XO-Lite? I might get some time for at least some simple features.

[olivierlambert]

Hi @konsultaner !

Let me ping the right person to assist on this

[Byscripts]

Hi @konsultaner.

I'll have to check with the XO Lite team to see what needs to be done, but I can already tell you how to set up the project and get on board.

1. Fork and clone the GitHub Repository
2. Go to the @xen-orchestra/lite directory
3. Copy the .env.dist file to .env and edit it to configure your XCP-ng server host URL (VITE_XO_HOST=http://...)
4. Install dependencies: yarn install
5. Run the dev server: yarn dev

If all has gone well, you should be able to access the XO Lite Dashboard from http://localhost:3000

Thank you.

[konsultaner]

why is this part of the commercial repo? what if the lite has some of the commercial features?

[olivierlambert]

what are you talking about? There's no "commercial repo" Xen Orchestra repo is where we store all the XO source code, and the whole code is aGPLv3. I don't understand why are you talking about a "commercial repo" ?

[konsultaner]

@olivierlambert I thought I need a license to use all features of XO? I didn't go through all the code. I have another project, that only provides non-commercial parts of the product in the official repo and the enterprise parts are in a private repo. So I wasn't sure if XO had all code hosted in that repo or just the free to use features? I wasn't ment to be offending, sorry.

[olivierlambert]

@olivierlambert I thought I need a license to use all features of XO?

No. It's even explained in our official documentation: see https://xen-orchestra.com/docs/installation.html#from-the-sources

If you git pull from our repo, and build it, you'll have absolutely all XO features. It's not open core, it's true open source. Our business model is creating XOA -Xen Orchestra virtual Appliance- (a dedicated VM bundled with QA and support). XOA brings extra features unrelated to XO, like an easy way to update it, stable/latest channels, and some stuff linked to your xen-orchestra.com account.

No worries and no offense

[Byscripts]

@konsultaner

The complete source code is open source and freely available with no paywall.

(And I don't think you were offending ^^)

Edit: too late

[konsultaner]

ok, cool. So yes, then it would be great to see what needs to be done. I can start off with adding a german translation

[olivierlambert]

Sure! A translation is a first good way to contribute Happy to have more people on board!

[ocktek]

Hello Oliver and thanks for your work.

Can we add a function to send a "ctrl-alt-del" to the vm in Xo Lite? Particularly for Windows server OS's that requires it in order to get logon screen.

Thanks.

[olivierlambert]

@ocktek sure, let me prioritize this
