Your guest setup is pretty much the same as the one I just built. I only have 
about 50 zones on this one but these are internal domains. The DNS servers act 
as outgoing for local clients.

I'm not sure that I should call it 'slow' but it's not as 'fast' as my stand 
alone's are, by a second or two perhaps.

I have a DNS measurement tool somewhere. The only reason I'm asking is because 
I want to be careful that I don't virtualize too much. If everything is even a 
tiny bit slower, then the overall will show up as sluggish services.
