With regard to this;

I've been hoping to create a set of updated KVM vs. Xen benchmarks as 
I've seen this asked for of late and existing data is >3 years old.
I would like to get the kernel setup relatively similarly to how it will 
be setup if/when an RPM is provided for RHEL 6.
These are the DEBUG entries I found in .config from your tutorial. Which 
are reasonable to set to n/m or just comment out? Did I miss anything 
else I should change? Again, I'm not looking to optimize, just to get 
closer to what the final generally available kernel will have.

I realize a bunch of these are for hardware that has little or nothing 
to do with Xen.
Thanks for any feedback.
