It's done. Now I am legally a Doctor of Philosophy (edit: no, I am not - still a PreDoc). Not much to say about the viva, I did not really prepare for it and there was no need, at the end. It was just an informal chat on my work, mostly detailing small corrections to apport to the thesis.
Next step is? Who knows? Relax in Sardinia, celebrate, then... may be start to look for an alternative position. I have some idea in mind, I'll share them in here very soon, as I get some more details fleshed out.
