[root@ops-1 ~]# curl  -s http://10.0.1.101/cblr/svc/op/ks/system/svab4 | grep nopxe

 
If so, can you verify that you see that request in your httpd logs?

no sign of 'nopxe'

might wget be missing?

i can add to %packages and try again.

That is entirely possible if you're doing a kickstart with --nobase or removing extra packages.
