Thanks! > A NET_TYPE_HOSTDEV device is really a hostdev device, the driver will create a hostdev device for it, so no need to create a libxl_device_nic again. Before this patch, it tried to call libxlMakeNic to create a libxl_device_nic for it but failed since NET_TYPE_HOSTDEV is not supported there.

I'll add this to commit message. Is that OK?
