Hello there.

[A small introduction] Me and my colleague as part of our graduation thesis have taken on a practical approach to use openstack to distribute OS images to the students of our faculty as lab working environments (just a rough description).

Being completely newbies on the matter, we ended up using devstack, hosted on a single node physical server which was given to us running Ubuntu Desktop OS. We also installed the KVM hypervisor to enable virtualisation.

[The actual question] We figured out how to spawn instances from images via dashboard and console seems to work just fine. What we would like to know is how to have a Graphical Interface of the OS's instance we want to launch? Clicking on "Console" opens an in-browser console which in the case of (let's say) Fedora image asks for login credentials that I don't have and I cannot understand as to why this happens because I expected to install the OS before anything else.

I'm not sure what image you're using... but my suggestion would be look into something like VNC (vnc-server). This is actually what the 'in-browser console' uses, but it's also usable without a browser.

Login credentials-wise.. you'll need to setup an ssh key pair to access your instances. Here's a good summary on how to do that:

Thanks for the part regarding the ssh key pair for the credentials I will look into that. One clarification though. In my initial question when I say "How is it possible to have Graphical Interface etc..." I meant not just SSH console. I do not consider this a UI. I meant icons & cursor and stuff.

Yes, that's what you need vnc for. If you access your image via ssh and install/start vnc, then you can install your windowmanager of choice.

If you're using a Fedora image with Gnome already installed, configuring vnc may be all you have to do. :)
