This document describes the investigation of a UDP packet loss / corruption issue in a virtualized networking environment.
While iperf is used as a controlled and repeatable test case, the issue is not limited to iperf.
Similar behavior has been observed in other UDP-based applications. iperf is used solely to demonstrate and quantify the issue.
