Thank you, Olaf.


I can understand the various blocks (except for "extra internal" and
"extra external"), but unfortunately I'm unable to relate them with
the numbers I showed in the first email.
For instance, I would say that the output of xenstore-ls reports is
related to the figure in the following way:
- "static-max" field: "baloon"+"guest"+"video" blocks,
- "target" field: "guest" block (that is, "build target" +/- "baloon")
- "videoram" field: "video" block

Instead, I'm really confused by the output of "xl top"

Any idea?

Cheers,

-- Marco
