I would recommend opening a case with TAC, make sure that when the time comes that TAC wants to do a remote session that you have your VMware person available as well.

It is. I had someone who is more knowledgeable than I am with VMware networking take a look at it.

Is the network assigned to the VM configured to support trunk?
The vSwitch and port group (assuming using VMware) configuration is important and pretty much non-negotiable.

Another odd issue I'm having is getting a trunk to work from Adapter 2/Gig0/0/0
On the controller I had the interface
G0/0/0
Switchport mode trunk
Switchport trunk allowed vlan 1-4094
(If put in a native vlan and left it at default with same results)
On the VM interface it was configured as a trunk with Vlans 1-4094.
Was there a trick or anything you had to do in order to get a trunk to work in this type of deployment? I've had a co-worked check the VM side and things looked correct on the VM network.

I recently helped a customer deploy a very similar environment (VDS), I still don't see the relevance of running multiple ethernet interfaces, you can use adapter 1 for management and then adapter 2 for you networking. Just deploy a second virtual controller on a different host if you want resilience.
We did run into an issue with NIC teaming, it is described in the link below. Check the third reply in the link below, to see if that get's you any further.

The VM environment is a virtual distributed system vs a single host like the deployment guides show. No one seems to be able to figure out where the issue is.

In that case, it doesn't make sense that two interfaces that are configured identical, connected (only one at the time) to a virtual ethernet in ESXi connected to the same vlan, that it doesn't work.
I can only think of a different configuration in the ESXi or the uplink switch where the vnics are connected to. As you mention that it's another VM adapter, is that different physical NIC and vSwitch on the ESXi? Please double-check the MTU/MAC-Change/Promiscuous settings on the NIC/vSwitch (check installation guides) and the settings on the upstream switch.
Can't imagine that this is a VMC problem.

Correct. I had only one interface active at a time. The typo was from me typing in my config. The system I'm using for remote access doesn't make it easy for me to copy paste the config so I typed it and had a typo apparently.

Assume you didn't enable both interfaces at the same time, as it would create a L2 loop?
Also not sure where the misspelled switchport turnk comes from? Did you copy this from the CLI output? I would expect switchport trunk.
