I do not have numbers I can share, but do have an interest in discussing 
methodology for evaluating "scaling"  particularly as regards to 
"networking."  My initial thoughts are simply starting with what I have 
done for "network scaling"  on SMP systems (as vaguely instantiated in 
the likes of the runemomniaggdemo.sh script under 
http://www.netperf.org/svn/netperf2/trunk/doc/examples/ ) though 
expanding it by adding more and more VMs/hypervisors etc as one goes.

While netperf (or its like) is simply a microbenchmark, and so somewhat 
removed from "reality" it does have the benefit of not (directly at 
least :) leaking anything proprietary about what is going-on in any one 
vendor's environment.  And if something will scale well under the rigors 
of netperf workloads it will probably scale well under "real" workloads. 
  Such scaling under netperf may not be necessary, but it should be 
sufficient.

happy benchmarking,
