Improving the Project Kronos pages

We had a look at the documentation for Project Kronos, and decided that it needed some significant improvement, so there’s been a good deal of rewriting and restructuring.

You’ll now find a Project Kronos main page, with an introduction to the project, and a set of pages linked off it detailing the steps needed to go from a plain Debian or Ubuntu installation through to a working Xen + XCP implementation and working guest VMs.

We’ve also combined the documentation for Debian and Ubuntu into one set of instructions, noting differences where relevant.

Hopefully, this is going to make life much easier for people looking to try out XCP.

We’ve also tried to clarify the differences between the two ways of using XCP: as an ISO to install a complete system, or as a set of packages to set the XCP toolstack up as an addition to an existing Linux installation (as per Kronos).

Letting the community know about Kronos

Now that we’ve got a page with instructions for Kronos on Oneiric (XAPI on Ubuntu), I was wondering about ways to let the community know that things are progressing. I’ve started with the simple step of adding some detail to the Xen page on the Ubuntu Community Documentation site, noting the availability of the new page. It could do with a good clear-out, but I don’t want to do that until we’ve got more, and better tested, instructions on the site.

Any other ideas are very welcome.

Kronos on Ubuntu – a nearly-n00b’s guide

As a long-term Ubuntu (and, before that, Debian) user, I wanted to try Kronos to see how easy it was to get Xen running on a standard Oneiric box for someone who didn’t have – and didn’t want – the detailed knowledge of the guts of the thing. Working with members of the team (very many thanks to Mike and Jon!), I’ve managed successfully to install and run Kronos on my home box.

The aim of the process was two-fold:
1. to see how to install Kronos on a standard (oldish, but decent spec.) home box, without wiping it out or making it unusable;
2. to document the process, with tips, warnings and suggestions.
My view is that if we can get Kronos to a position where it’s plausible for a fairly knowledgeable Ubuntu sysadmin-type user to install it and start playing with it, then people will just have a play with it. If we require people to come to the party with a high spec, new, clean, dedicated box, then we’re going to have fewer people trying it out.

It took some doing, but (again, thanks largely to Jon and Mike), I’ve had success, and I’ve documented what I did over on the wiki. Please look at it, try it, improve it, and critique it. Hopefully we can make it more and more useful, and as Precise (12.04) comes along, things should get even easier.

My plan is to keep trying things out, working with the team as a naive-ish user, and helping to improve Kronos through testing and documentation. I’d welcome any thoughts and suggestions

One note: though I’ve tried to be as careful as possible, and to provide sensible warnings, any damage to your system is on your own head!
