  • Thread-topic: Learning DomU memory usage from Dom0


I have been trying to learn domU memory usage from dom0. I have tried 
to achieve that by reading to read memory usage via xentop. Xentop only
shows allocated memory data. 

I have also tried to send it from domU to dom0 via xenstore. I had some
trouble with xenstore permissions.
For example i had two domU's 27 and 31.
I created a /tool/ramusage/27 path from dom0
And used xenstore-chmod /tool/ramusage/27 w27 so domU 27 can write to it.
But domU 31 could also write to it. Could it a bug or am i missing something
about xenstore permissions.

Beyond that is there a better way to learn this data ?

Thank you very much.
