how does Real-time Linux and (Xen) Virtualization work together?

how does Real-time Linux and (Xen) Virtualization work together?

[Gautam Thaker]

how well would a set of 2 real-time Linux guest OSes
work on top of a dom0 host that would be based on
real-time linux? Has real-time and virtualization
interactions been studied in any details? I am not
even sure if a real-time Linux can be the host OS for
hosting  guest OSes, can it?

Best case, it will work as well as Xen's scheduler and internal locking
allows.
