Great! :-)

Ok, I'm fine with this. Looking at make-flight, we seem to want to be
able to run tests on Xen 3.*, 4.0, 4.1. As I said in my email, I can't
speak for these. I honestly think that SEDF was already broken, so I
personally would be more than glad to send a patch that gets rid of it
all the way, but that does not count much, I guess, as I wasn't here!

As soon as you (and others) will let me know what's best, I'll do it.

Patch coming. I'm not removing the interfaces and the symbols, to allow
backword build-time compatibility to be retained, but yes, I'm removing
it from everywhere, and "neutralizing it" (just in case!) in libxl...
You shall see! :-P

Thanks and Regards,
