Create Devstack VM

This repository contains two Ansible roles for automating the creation of VMs that run devstack. Simply run the setup_vm.sh script with the desired name of the VM as an argument, like for example ./setup_vm.sh c9s-debug. Then, Ansible will ask you to enter the sudo password for the local host.

Note

Make sure SSHD is running on your local host before running the script.

Installation

This script should work with ansible 2.12 or newer. To install the roles it depends on you can run:

$ ansible-galaxy install -r requirements.yaml

Image Preparation

The standard CentOS Stream 9 cloud image has only a 10G file system. To be useful it should be resized to at least 20G. These commands will resize it to 25G:

qemu-img resize image.qcow2 +15G
cp image.qcow2 image-orig.qcow2
virt-resize --expand /dev/sda1 image-orig.qcow2 image.qcow2

Variables

The following list shows configuration variables and their defaults.

• ds_base_dir: "{{ lookup('env', 'HOME') }}/VM"
• ds_base_img: "CentOS-Stream-GenericCloud-9-20220211.1.x86_64-ResizedOnly.qcow2"
• ds_ssh_pubkey_path: "{{ lookup('env', 'HOME') }}/.ssh/id_ed25519.pub"
• ds_reclone: "False"

• ds_sync_folders:

  • barbican-tempest-plugin
  • designate-tempest-plugin
  • devstack-helpers
  • octavia
  • octavia-dashboard
  • octavia-lib
  • octavia-tempest-plugin
  • ovn-octavia-provider
  • tempest

• ds_test_server_path: "{{ lookup('env', 'HOME') }}/openstack/test_server.bin"

ds_base_dir is use as a base directory when creating files on the local host. The base image configured with ds_base_img must be store in there. ds_sync_folders lists the subdirectories of ~/openstack that should be synced with the VM.

You can overwrite the default value by adding them as key=value arguments when running the setup_vm.sh script:

$ ./setup_vm.sh c9s-debug ds_base_dir=$HOME/devstack ds_base_img=myimage.qcow2

Output of stack.sh

restack.sh may take a long time to finish. By running less +F ~/devstack/output.log in the VM while Ansible runs the script one can see the current status. This file is also helpful for debugging in case the script does not succeed.
