otopi Machine Dialog Parser for python

This module allows you automate installation process based on otopi installator.



WARNING: The otopi package is not hosted on PyPi site, so it couldn’t be included as dependency of this package. It is maintaned by oVirt community, they ship this module for several package managements.


  1. Set otopi environment to enable machine dialect

  1. Spawn desired installer and pass stdin and stdout to parser

  2. Process all otopi events in the loop

Example for oVirt Hosted Engine

import subprocess
import otopimdp as mdp

# 1. Set machine dialog option
with open("/etc/ovirt-hosted-engine-setup.env.d/mycustom.env") as fd:
        'export environment="${environment} DIALOG/dialect=str:machine"\n'

# 2. Spawn installer
installer = subprocess.Popen(["hosted-engine", "--deploy"])
parser = mdp.MachineDialogParser(
    input_=installer.stdout, output=installer.stdin

# 3. Process events
while True:
    event = parser.next_event()
    if event is None:
    event_type = event[mdp.TYPE_KEY]
    if event_type == mdp.TERMINATE_EVENT:

    event_name = event[mdp.ATTRIBUTES_KEY]['name']
    if event_name == "OVEHOSTED_HOST_ID":
        event[mdp.REPLY_KEY] = "1"

Run tests


NOTE: For testing purposes, the otopi package is being run from sources.
