I was just wondering if Xen and Realtime ("rt-" linux kernel, aka.
realtime-preemption) work fine together?
(In the easiest use-case: the host providing realtime priority to
a single guest OS, and that guest OS can provide rt guarantees to its
Or is this unfortunately not feasible right now?
Thank you much,
