This is a Management Node
dbengine=SQLite

With netboot=pxe I was trying to assign an image:

nodeset node3 osimage=ubuntu16.04.4-x86_64-install-compute
Error: Unable to find pxelinux.0

I've dug a bit, and found mentions of pxelinux.0 in xCAT-server/lib/xcat/plugins/pxe.pm
It was checking two directories /usr/lib/syslinux/pxelinux.0 and /usr/share/syslinux/pxelinux.0 but neither existed on my system.

I've tried to installing the syslinux package, but that didn't help.

After copying the file directly to one of the above-mentioned directories
cp /opt/xcat/share/xcat/netboot/syslinux/pxelinux.0 /usr/share/syslinux/pxelinux.0
the error disappeared:

nodeset node3 osimage=ubuntu16.04.4-x86_64-install-compute
Warning: rcons may not work since no serialport is specified for rainbow3-10.bru
node3: install ubuntu16.04.4-x86_64-compute
