Hi
I have a question regarding ability of a domU to read Xenstored. Is it possible for domU to read some of the values from xenstored? like its own domID? Or some other information? To be more specific can a simple user level program like get_my_domID.C do it? Or do we have to write some kernel module to do that job? With my setup of virtual machines, I am 'not at all' concerned about the security.

The question arises from the fact that (obviously it is not openly possible) that how can a domU know what dom0 is it on, especially if domU wants to broadcast its host to other domU's? I totally understand this is not supposed to be in Xen architecture, so please don't ask why I want to do this :).

I also understand this question has been asked so many times in the list, but I am not able to find any definitive answer.

Best Regards,
Atif
