How to run a managed object reference function?

[SomniVertix]

Looking to use the following method from the vsphere API:

https://vdc-download.vmware.com/vmwb-repository/dcr-public/b50dcbbf-051d-4204-a3e7-e1b618c1e384/538cf2ec-b34f-4bae-a332-3820ef9e7773/vim.host.NetworkSystem.html#queryNetworkHint

It says that its called from the "HostNetworkSystem" managed object, but whenever i try that it errors saying that it doesnt have that function.

Example code:

	Run(func(ctx context.Context, c *vim25.Client) error {
		// Create a view of HostSystem objects
		m := view.NewManager(c)

		v, err := m.CreateContainerView(ctx, c.ServiceContent.RootFolder, []string{"HostNetworkSystem"}, true)
		if err != nil {
			return err
		}

		defer v.Destroy(ctx)

		// Retrieve summary property for all hosts
		// Reference: http://pubs.vmware.com/vsphere-60/topic/com.vmware.wssdk.apiref.doc/vim.HostNetworkSystem.html
		var hns []mo.HostNetworkSystem
		err = v.Retrieve(ctx, []string{"HostNetworkSystem"}, []string{}, &hns)
		if err != nil {
			return err
		}

		for _, hn := range hns {
			hn.QueryNetworkHint()
		}

		return nil
	})

You can't use HostNetworkSystem with ContainerView

type - An optional list of managed entity types

Where managed entity is VirtualMachine, HostSystem, etc.

HostNetworkSystem is a property of HostConfigManager, which is a property of HostSystem. And HostSystem is managed entity.

The generated mo.HostNetworkSystem does have methods attached to it (likewise for other mo types), but you can use the object package to simplify fetching of the properties you need and invoking the method:

	simulator.Run(func(ctx context.Context, c *vim25.Client) error {
		m := view.NewManager(c)
		kind := []string{"HostSystem"}

		v, err := m.CreateContainerView(ctx, c.ServiceContent.RootFolder, []string{"HostSystem"}, true)
		if err != nil {
			log.Fatal(err)
		}

		refs, err := v.Find(ctx, kind, nil)
		if err != nil {
			return err
		}

		for _, ref := range refs {
			hn, err := object.NewHostSystem(c, ref).ConfigManager().NetworkSystem(ctx)
			if err != nil {
				return err
			}
			info, err := hn.QueryNetworkHint(ctx, nil)
			if err != nil {
				return err
			}
			_ = info // ...
		}

		return v.Destroy(ctx)
	})
