Hello everybody:

When I build guest OS for D0 and DU, I found that they did not support CONFIG_SCHED_MC.

I think that if they support CONFIG_SCHED_MC, there will be more VCPU idle, and it is good for power management.

So, I do not know why guest OS of xen forbids us to use CONFIG_SCHED_MC.

I use Xen-3.3.0 and Linux-2.6.18.8 for guest OS.

Thank you very much!
