python host.create_host_only_network_interface returns bad object

[silvermangb]

vbmanager = virtualbox.Manager() vbox = vbmanager.get_virtualbox() host = vbox.host

hoa,progress = p_host.create_host_only_network_interface() progress.wait_for_completion(32000)

print hoa.name

The print statement generates an error

Failed to find attribute name in <virtualbox.library.IHostNetworkInterface object at 0x0000000008FB6898>

However, the interface was created.

I used pyvbox, installed by pip.

This problem occurs on Windows 10, but, the same code works in El Capitan.
