* Add ipxe.efi to dnsmasq image's /var/lib/tftpboot directory * Add initrd kernel argument respected only by UEFI https://github.com/coreos/bugs/issues/1239 * Improve network-setup docs and scripts to cover UEFI clients and to support launching UEFI QEMU/KVM clusters locally * Reduce references to grub.efi flow, its not a happy path

libvirt
Create QEMU/KVM VMs which are configured to boot from the network. The scripts/libvirt script will create virtual machines on the metal0 or docker0 bridge with known hardware attributes (e.g. UUID, MAC address).
$ sudo ./scripts/libvirt
USAGE: libvirt <command>
Commands:
create create QEMU/KVM nodes on a rkt CNI metal0 bridge
create-rkt create QEMU/KVM nodes on a rkt CNI metal0 bridge
create-docker create QEMU/KVM nodes on the docker0 bridge
create-uefi create UEFI QEMU/KVM nodes on the rkt CNI metal0 bridge
start start the QEMU/KVM nodes
reboot reboot the QEMU/KVM nodes
shutdown shutdown the QEMU/KVM nodes
poweroff poweroff the QEMU/KVM nodes
destroy destroy the QEMU/KVM nodes
k8s-certgen

$ ./scripts/tls/k8s-certgen -h
Usage: k8s-certgen
Options:
-d DEST Destination for generated files (default: .examples/assets/tls)
-s SERVER Reachable Server IP for kubeconfig (e.g. node1.example.com)
-m MASTERS Controller Node Names/Addresses in SAN format (e.g. IP.1=10.3.0.1,DNS.1=node1.example.com)
-w WORKERS Worker Node Names/Addresses in SAN format (e.g. DNS.1=node2.example.com,DNS.2=node3.example.com)
