I think you want params.CpuTopology. I can't work out how to actually
add that to the VM creation request though, I assigned it to the cpu
parameter and didn't get an error but I also didn't get a VM with
the assigned number of cores/sockets.

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)
