Plugins » Discovery

I was trying PXEless discovery. I started the instance via fdi-image-3.0.1.iso and selected "Discover using DHCP". As soon as I gave the foreman-server URL and clicked next. I got following on 'Discovery Status' screen:

Status - Failure - awaiting kexec into installer

Server response was 422 with error: 
Reloading kernel on mac52540093cdda.idmqe.lab.eng.bos.redhat.com task failed with the following error: undefined method 'facts' for NilClass::Jail (NilClass)

production.log filled with error:
