PXE WDS in VirtualBox

I am trying to learn how to use WDS.  I have a lab environment set up with a DC that has DHCP and WDS installed.  WDS is configured to respond to all clients, and require admin approval for unknown computers.  I have an install image and boot image loaded.  The server and test client are running in VirtualBox.

For my test client I have enabled network boot in the VirtualBox settings.  However, when I start the client all I get is a blank screen with a solid white underscore (as attached).  When i start up a server core test box my DHCP is working just fine.  Any ideas as to what I'm doing wrong?

Thank you!

for troubleshooting: did you set the dhcp options for WDS
 You must tell WDS not to listen on port UDP 67 an d set option 60 in DHCP.
Since you are telling WDS to wait for admin approval for unknown computers.. is this computer showing up in WDS as waiting authorization? or did you pre-configure the MAC address in WDS?

I did set dhcp during the wds installation wizard- but I thought for approval on unknown systems that would show up on the client side.  Is that a server side thing I look at?

I just tried to prestage the client - and i'm still getting the blank box with an underscore on it :-(

Thanks for your help!  Turns out switching to Hyper-V from VirtualBox solved the problem I was having.  My system is responding now, thank you!
