We're using Kea and iPXE to do cross-site provisioning so I'm not sure what's 
not working for you. One thing I did run into early in testing was having to 
use the kpxe shim (I think that's the suffix, it's one of the binary variants 
generated by the makefile and not the default one) because the DHCP request 
packet from iPXE and preseed were subtly different enough that Kea would create 
two leases ... but once we got that, it's been solid to the tune of several 
hundred devices ...
I can share parts of my config if you're interested; I did end up using a beta 
version in our application because it had additional option parsing logic 
operators, but those have been merged into the released version in the 
meantime.

HI all-

I am looking into replacing ISC DHCPd with Kea in our dev lab.  One of the 
primary requirements is iPXE chainloading - in other words, the PXE ROM on the 
NIC must be able to download and execute iPXE over the network.

I've setup a simple test environment in VMware Workstation 12.5:

| ---------------- |
| Kea 1.1 VM     | ens37
|  CentOS 7        |----------------------| Test VM 
| ---------------- |
         | ens33
         | 
         |
    outside

The interface configuration is 
"interfaces-config": {
    "interfaces": [ "ens37" ]
}

I have the packet captures if anyone is interested.

Any help is much appreciated and thanks ahead of time,
roy
