I do plan on coming back to finish and flush out more explanations but till then good luck. If really do have honest questions ask them in the comments and I'll answer what I can.

VEM may drop Cisco Nexus 1000V ARP request from VM.

Revised understanding of the issue of 30secs of working and 30secs of reset
putting a single nic in a port channel causes it to behave 30 seconds up and then 30 seconds down, this has be recreated. the speed setting has nothing to do with it. and the Auto Negotiation being seen in the log was just after the 30 sec fail.

Before you can disable Vpc (Virutal port channel) you must remove all but one nic it from the Distubed switch in ESX.

VEM commands can be run remotely from the VSM (v1000)
module vem 3 execute show port
