# What ? This kickstart file provides the base configuration for a guest hypervisor. 
# It requires the Fedora 34 server iso
# 'i' for iso-based, 'v' for virtual machine, 'h' for hypervisor', 'm' for minimal, 'd' for development only.

# USAGE : Press the `tab` or 'e' key during POST and apend that after the 'quiet' string : 
# inst.ks=https://git.phyllo.me/home/kickstart/raw/branch/master/leaves/ivhmd.cfg

# ATTENTION : this kickstart file will automatically DESTROY the main virtual disk 'vda' and all of its contents. 
# Bye bye!
