I need less than 10 bits at rate of 10 milliseconds. With a random number I will select the next VCPU to schedule.

How many bits do you random numbers need to be?

At what rate do you need them? (10/second?, 1000000/second?)

Would pseudo-random numbers do? If so, what repeat interval is
sufficient?
