With the new credit scheduler checked into the xen-unstable tree, I 
wouldn't recommend to use either BVT or SEDF. They're both buggy. The 
new scheduler is supported by us, automatically load balances on SMP 
systems, and has a simpler administrator interface. Once credit 
scheduler has demonstrated its stability we'll most likely remove the 
other two schedulers.
