Ian, It looks like you are trying to setup a basic zone and have a Management Server on IP 192.168.101.3 and a Host on IP 192.168.101.4.
The second interface on the host does not need any IP configuration on the Host as it will not be used by the Host so remove the 192.168.102.4 mapping.. This interface will be used by the Guest VMs running on the Host who will have their own IP schema. Your Guest IP range will be in the 192.168.102.0/24 CIDR with a gateway of 192.168.102.1 The Management Serve will talk to the Host via the 1st Interface, and Guest VMs will use the 2nd. You have not mentioned storage, but assuming you are using NFS for Primary and Secondary, put the NFS Server on the 192.168.101.0/24 network, and then all storage traffic will also go over the 1st interface.

Maybe you should swap them. This is only guessing however. What are you seeing?
