I have set-up xen on my Intel quad core server. Now running different experiment to measure network throughput in virtualized environment. these are some of the results:

Netperf-4.5 results for inter-domain communication.

Sr.No.              Client             Server         Time(sec)        Throughput(Mbps)
   1                   Guest-1              Dom0                    180                            2398 - 2500
   2                     Dom0             Guest-1                   180                            1636 - 1883    3                     Dom0               Dom0                    180         2200
4                     Guest-1           Guest-1                   180                                 1921

5 Guest-1 Guest-2 180 0.14 - 0.29

You can see throughput is ok in all cases else Guest to Guest communication.
If anyone has some idea, please share. What could be the reason?
