I keep forgetting kernel boot options for booting RHEL 7 installations.
Here is the URL that describes kernel boot options for RHEL 7. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/installation_guide/chap-anaconda-boot-options
Here are some parameters I use frequently.
Installing from USB (inst.stage2) and specifying a static IP (inst.ip):
inst.stage2=hd:UUID=2018-05-07-15-34-45-00 ip=10.5.40.14::10.5.40.1:255.255.252.0:kwrtest:enP3p9s0f1:off inst.vnc
