Hi! I have two questions: 1) Does you VM environment over-commit CPUs (i.e. doe you have more virtual CPUs than physical CPUs)? 2) Do you use multicasting ot unicasting? In the past multicasting wasn't really reliable. Generally VMs are not really best for real-time applications (anything that relias on real-time scheduling) IMHO.
