Hello,
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
applications?)
Or is this unfortunately not feasible right now?
Thank you much,
Mats

Would this be an appropriate question to ask xen-devel, xen-community,
xen-research, or none?
