#  rhcos_install_img_url: # Where to grab rhcos install http://<host>/<path>/rhcos/rhcos-4.3.8-x86_64-metal.x86_64.raw.gz
#  rhcos_ignition_file_url: # where to find ignition file http://<host>/config/rhcos/bootstrap.ign #to be modified based on group or host level, for bootstrap, master, etc
#  rhcos_install_url: #where kernel/initrd.img and .treeinfo are to be found, internal
#  kvm_guest_vcpus:
#  kvm_guest_memory:
#  kvm_guest_disk_size:  #in GiB, not to be added, so example: 120
#  kvm_host_bridge: # which defined bridged to use for the guest vnic
