Hello,
As of now, Xen does not support admission control for the SEDF scheduler.
For example, 2 Domains having a slice of 10 ms and a period of 15 ms can
coexist, although it is impossible to honor these scheduling parameters.
I have developed a patch, which warns the user if the scheduling parameters
cannot be honored in case of SEDF scheduler. This is for a single CPU.
I want to extend this to multiple CPUs. I would like to know how XEN SEDF
deals with multiple CPUs.
Thanks,
Vishal
