Hello-
I am working on a project to modify Xen to precisely control the execution times of the individual guest domains, and I need some help. I considered modifying the XM python program, but it is not precise or fast enough for my application.

I want to be able to pass short, simple message quickly between an application-level process and the Xen kernel asynchonously. I found an IPC mechanism designed for the method called netlink (http://www.linuxjournal.com/article/7356), but I am not sure how to incorporate it into the Xen kernel. When I attempt to recompile the kernel with netlink, I get errors that seem to stem from type issues I am not familiar with.

2 questions:
Is it possible to use a mechanism such as netlink with Xen? If so, how?
Is there other functionality within Xen that could be used with minimal modification to do IPC within domain0?

Any help/advice would be greatly appreciated. Thanks!
--Derek
