Hi,
  I am newbie to the XEN environment. I am setting up a system (with a
single CPU) with 3 individual domains. I am using the sedf scheduler,
and specifying its paramters using xm:
  xm sched-sedf <dom-id> <period> <slice> <latency-hint> <extra> <weight>
  I am able to create invalid configurations like
  Dom 0 = slice:4 period:10
  Dom 1 = slice:4 period:10
  Dom 2 = slice:4 period:10
  In my single core machine, I realized that it may not be possible to
realize such a configuration since the total request exceeds the
capacity. Are there any error messages or warnings generated during
such mismatched settings? If so, how do I view them? Thanks for your
help, since this will enable me to look for mismatch in dom
configuration in the future.

Thanks again,
Karthik
