xCAT is using genesis (an xCAT customized pxe tool) to function the discovery process. The configuration for genesis is put in /tftpboot/xcat/xnba/nets/ for a specific network. Could you check your specific xnba configuration file for your deployment network has been put in /tftpboot/xcat/xnba/nets/?
The prerequisite for booting of genesis is to make the node has a dynamic IP address. Did you configure the dynamic IP range for your deployment network? Could you take a look of your syslog to see whether the node has sent out dhcp request and what did your dhcp server replied to them?

I'm attempting to do a sequential nodediscovery. I've pre-populated the nodelist table with the nodenames, so I shouldn't need to do anything more than nodediscoverystart noderange=node[1-15] However, none of the nodes ever gets discovered. Digging deeper, it seems that none of them ever successfully PXE boot at all. They should be PXE booting off of the genesis netboot image and speaking back to the xcatmaster, correct? When I run 'mknb x86_64', it populates /tftpboot/pxelinux.cfg with entries to non-existent netboot images.
