VMEmperor

Configuration

File: configs/config.ini

Example

debug = True # Debug
username = 'root' # XenServer root username
password = '!QAZxsw2' # XenServer root password
url = 'http://10.10.10.18:80/' # XenServer API URL
database = 'vmemperor' # RethinkDB database name
host = '127.0.0.1' # RethinkDB host
vmemperor_host ="10.10.10.102" # Your host's IP as seen by VMs (for postinstall script URL)
vmemperor_port = 8889 # VMEmperor API port
authenticator = 'ispldap' # Authenticator class
#authenticator='ispldap'
#log_events = 'vm,vm_metrics,vm_appliance,vm_guest_metrics.sr,vdi'
ansible_pubkey = '~/.ssh/id_rsa.pub' # Public key exported during auto installation for Ansible
ansible_networks = ["920b8d47-9945-63d8-4b04-ad06c65d950a"] # Networks that your host and VMs all run on
user_source_delay = 2 # How often VMEmperor asks external authenticator for user and group lists, in seconds

How to configure with Docker

  1. Configure login.ini. Leave the following options default:
    • vmemperor_port (Dockerfile assumes auto configuration of frontend and it uses default port)
    • host (Dockerfile assumes RethinkDB is running in the same Docker container)
  2. Pay attention to ansible_pubkey variable: its default value assumes that you mount /root directory with .ssh/id_rsa and .ssh/id_rsa.pub files in container. If you change this value, correct docker run command accordingly
  3. Adapt your Ansible playbooks, see example in ansible folder. You may want to use them as volume - edit docker-compose.yml
  4. Generate SSH keys for access using Ansible:
ssh-keygen -f keys/id_rsa
  1. Run docker-compose up

How to configure (without Grafana)

Grafana is only available with docker-compose

  1. Ensure at least Python 3.7 on your host machine

  2. Set Up XenServer and provide XenServer URL as url config parameter

  3. Set up RethinkDB. Don't forget bind=127.0.0.1

  4. Install ansible in order to use automation benefits

  5. Generate a SSH pubkey for ansible to use

  6. Set up config parameters as shown in Example

  7. Set up API URL for frontend: in frontend/server/index.js find:

    const options = {
  target: 'http://localhost:8889',

    around line 38 and replace it with http://localhost:vmemperor_port (or another host if you plan to use frontend and backend on different hosts)

  8. Start RethinkDB

  9. Install VMEmperor dependencies with pip install -r requirements.txt (optionally create a virtualenv ). Install npm for managing frontend

  10. For ispldap set up LDAP server IP in auth/ispldap.py:12, variable SERVER_IP

  11. Optionally Adapt your Ansible playbooks, see example in ansible folder

  12. change your directory to /backend and copy /configs/config.ini to there.

  13. Start VMEmperor with python3 vmemperor.py

  14. from frontend directory install dependencies with npm install

  15. run frontend with npm run start
