[gPXE] No network devices found when using gpxe and virtualbox

[Nathan Mitchell]

Okay guys,

         Here is a strange one. I'm putting together a series of virtual machines for testing some boot management software. We have the setup mirrored with physical hardware, so 
   I know it works. 

         The basic setup is one machine will run several virtual machines and when they boot they need to load gpxe from tftp. This part works, gpxe is successfully found and loaded, 
   thus the network functions up till this point. However, once gpxe loads and probes for network interfaces, it displays the "No more network devices" message. Just the header and that message. 
   I am at a loss as to what is going on here. I've tried different virtual network cards and even loading gpxe as the vm's rom - all have produced the same results. Now I've seen other people use
   gpxe with virtualbox and even the wiki has instructions ( those I followed for the rom ), so I believe its possible but I must be doing something wrong. If anyone has any ideas on how I might figure out
   whats happening here, I'd be most grateful.
