Worked it out. You need to define the CPU topology parameters:

    vm_cpu_top = params.CpuTopology(cores=2, sockets=2)

Then use that to define the CPU parameters:

    vm_cpu = params.CPU(topology=vm_cpu_top)

Finally you pass that in your VM creation request (assume here that I have set the other vm_* variables referenced earlier):

    vm_request = params.VM(name=vm_name, memory=vm_memory, cluster=vm_cluster, template=vm_template, os=vm_os, cpu=vm_cpu)
    vm = api.vms.add(vm_request)
