*** Bug 1670302 has been marked as a duplicate of this bug. ***
The issue was still seen in Satellite 6.5.0 snap 15. ``` There was an error rendering the Discovery Red Hat kexec template: undefined local variable or method `append' for #<Foreman::Renderer::Scope::Provisioning:0x0000000012330038> ```
Verified! @ Satellite 6.5 snap 18 Steps: Scenario1: 1. Provisioned a Host on local libvirt. 2. Attempted to render/preview the kexec template. Behavior(Expected): 1. The template is rendered successfully as: ``` { "kernel": "http://example.com/pulp/repos/Default_Organization/Library/rhel7_cv/custom/rhel76_prod/rhel76_repo//images/pxeboot/vmlinuz", "initram": "http://example.com/pulp/repos/Default_Organization/Library/rhel7_cv/custom/rhel76_prod/rhel76_repo//images/pxeboot/initrd.img", "append": "ks=http://example.com:8000/unattended/provision&static=yes inst.ks.sendmac ip=::::::none nameserver= ksdevice=bootif BOOTIF= nomodeset nomodeset", "extra": [] } ``` Scenario2: 1. Discover and provision the pxe-less host. Behavior(Expected): The host is discovered and provisioned as kexec(without booting) and didn't see the freezing as BZ #1670302 says.
