Mickael Salaun made a proof of concept of a covert channel with a code written in C : xencc.c.
This code was writtten in 2009 and is accessible here : http://digikod.net/public/XenCC/

This code permit to send data between 2 domU using Pseudo-physical memory with a driver created by xencc.

Can you say me :
- if you made a patch or a fix for this problem ?
- if yes, in which Xen version did you implement it ?
- if yes, by which manner (mecanism) did you fix this problem ?

Thanks in advance for your answers.
