Undercloud preparation (on the KVM host)

set password & subscription information

export USER=YOUR_RHEL_SUBS_USER    
export PASSWORD=YOUR_RHEL_SUBS_PWD
export POOLID=YOUR_RHEL_POOL_ID
export ROOTPASSWORD=UNDERCLOUD_ROOT_PWD
export STACKPASSWORD=STACK_USER_PWD

install basic packages

yum install -y libguestfs libguestfs-tools openvswitch virt-install kvm libvirt libvirt-python python-virtinst

start virsh

systemctl start libvirtd

create and become stack user

useradd -G libvirt stack
echo $STACKPASSWORD |passwd stack --stdin
echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack
chmod 0440 /etc/sudoers.d/stack
su - stack

create ssh key

ssh-keygen -t dsa

adjust permissions

sudo chgrp -R libvirt /var/lib/libvirt/images
sudo chmod g+rw /var/lib/libvirt/images

get rhel 7.3 kvm image

goto: https://access.redhat.com/downloads/content/69/ver=/rhel---7/7.3/x86_64/product-software

Ironic Node definiton

Option 1

define nodes in instackenv.json (option 1)

(https://access.redhat.com/documentation/en/red-hat-openstack-platform/10/paged/director-installation-and-usage/chapter-5-configuring-basic-overcloud-requirements-with-the-cli-tools)

vi ~/instackenv.json

import nodes

openstack baremetal import --json ~/instackenv.json

Option 2

define nodes with CLI

ssh_user=stack
ssh_key=SSH_KEY_OF_SSH_USER (/home/stack/.ssh/id_dsa on kvm host)
num=0
