System A is physical server & System B is IVM guest. Network Details are as below :-

Is there any ping drop/latency between these two machines?

This happens using names or IP addresses?
In the case of you are using names, do you have configured at least /etc/resolv.conf and /etc/nsswitch.conf files?
Rgds.
