Hi Shawn,

Your attempt is complicated substantially by running the LTSP server 
within a VM.

* The interface that you attach to ltspbr0 in the server VM needs to be 
a secondary virtual eth device, not the primary that the VM uses to 
reach the Internet.
* Then on the VM host, that secondary virtual eth device needs to attach 
to an entirely separate bridge that probably doesn't already exist on 
your system.   This new bridge that you must create must not have any IP 
address.  It exists only for VM's to connect to each other.
* Then the PXE client VM must connect to that new bridge.

If you set this up properly, then server VM's ltspbr0 connects to the 
virt host bridge, and the PXE client VM can also connected to that same 
bridge should be able to DHCP and PXE boot.
