Setting network fails

[robinbowes]

I'm setting the network for a new VM as follows:

  config.vm.provider :vcenter do |vcenter|
    vcenter.hostname = vcenter_host
    vcenter.username = username
    vcenter.password = password
    vcenter.network_name = network_name
    vcenter.linked_clones = true
    vcenter.disable_auto_vm_name = true
    config.ssh.pty = true
  end 

The network is not changed, ie. the VM comes up with the network that was saved in the template.
