Oh, great!

And now I've had a look at it.

Yes, and it's a really nice writeup of that.

I'm not sure either. I'd say that the post as it is, even better with
a/some diagram, is already a really nice one. The only thing that
puzzles me in this case, is that it, yes, describes what PoD is and how
it functions, but, since the user can't really do nothing about or with
PoD (or can he?), it'd all be for the sake of knowing it, which may be a
bit weak of a motivation. Of course, if there were the technical and
implementation details, that would be "fixed", but I don't know how much
time and effort it's required be to add those.

TBH, I really would like to have a more technical and implementation
focused post about this, as I think it's something important that not
many dominate, and because it's a while we haven't had a 'Xen internals'
post. Of course, we can make this a process with two phases, the first
one of which is what you have, the second is the more technical
description.

On that ground, and if you're up to writing "episode II" (in a few
weeks, of course, e.g., when it will be your turn to blog again!), I'd
say, stick there a few hyperlinks, a cool (and copyleft) photo of some
balloons, a diagram --if possible-- and go for it!

Does that make sense?

Oh, if doing it this way, one thing that I'd mention, at the bottom, is
what happens in PV. Just very lightly and quickly, but I guess, since
you mention HVM, someone not super-knowledgeable about the Xen
architecture, while being perfectly able to follow the post until there,
could wonder something like: <<why only in HVM guests? how is the thing
different in PV guests?>>

Thanks and Regards,
Dario
