Foreman Discovery Plugin

I have edited the PXE global default template like this:

LABEL discovery
MENU LABEL Foreman Discovery
MENU DEFAULT
KERNEL boot/fdi-image-rhel_7-vmlinuz
APPEND initrd=boot/fdi-image-rhel_7-img rootflags=loop root=live:/fdi.iso rootfstype=auto ro rd.live.image acpi=force rd.luks=0 rd.md=0 rd.dm=0 rd.lvm=0 rd.bootif=0 rd.neednet=0 nomodeset proxy.url=https://mysat:9090 proxy.type=proxy
IPAPPEND 2

Before I edited the template I took the iso from the tftpboot directory on the sat server and mounted it on a VM to test. When I start up the VM I select Manual Network put in my network information (we don't use DHCP) and its awaiting the kexec. It shows up in my Discovered Host I click on "Provision" and change the Name and Select the appropriate host group and click submit.

The VM reboots and brings me right back to the "Manual Network" setup again instead of starting the install of the OS. I know I'm doing something wrong. Could someone please help.

After I changed the template and click "Build Default PXE" do I need to get the new image from the Sat Server.

Thanks
