[libvirt] Libvirt node is not getting booted through network

Hi, I am trying to boot my node through network with the following configuration: But I am getting an error message saying: Even my network setting is not getting reflected in the Virtualbox. Can anyone suggest me what is wrong with this configuration. I think to boot a node from network we need to define a boot server but where shall I add that, I am confused.... Any help will be appreciated. Thanks in advance.
