So, somewhere in my troubleshooting, I got myself confused.  This 
morning I decided to reduce as much as I could, like Russ suggested.  
However, because this is a large production environment at work, I 
couldn't exactly go moving things to hubs and such. Instead I made sure 
that everything was on the same cluster (I initially was building the 
client in a different cluster than the servers).  As soon as I did that, 
the build took off without issue.

I then went back and looked at the clusters and networks.  When I looked 
at the build VLAN, I found out it was only attached to the server 
cluster and not to the client cluster.  It is defined at the data center 
level, so Satellite/Foreman let me create it and assign it to the VM 
template, but when it actually created the VM, it didn't have an actual 
network to attach it to, so it just left the network blank.

When I thought I saw the traffic on one server yesterday, I must have 
been seeing something else and didn't realize it.

Now, I've got the vSphere admin defining the build network on both clusters.
