You need to do proper research before saying things that are not true. My PowerEdge 2950-III is SUPPORTED by DELL until December 2014. Furthermore, ESXi 5.1 update 1 is SUPPORTED on Dell PE 2950-III.
The VM in question is one of the multicast recipients.
At the moment, they are going to move the multicast applications from the VM over to the physical machines.

We use a fair amount of multicast applications, and have never had issues with dropped packets.
How do you determine that you don't have issues with multicast packet lost? Do you capture the multicast on both ends and decode them and count the result. if you do, I am willing to bet that you will definitely packet lost. I put sniffer trace on both end and that how I confirm that there are lot of multicast packet loss. You can see the packet hitting the ESX NIC but got lost somewhere along the vmware vswitch.
