Testing ovirt-engine changes without a real cluster

The ovirt-engine component of oVirt is the brain of oVirt and is responsible for managing attached systems; providing the webadmin UI and REST interfaces; and other core tasks. The process of setting up a real cluster on which to deploy the project is a time-consuming task that greatly increases patch turnaround time and can provide a significant barrier of entry to those wanting to contribute to the project.

Development Environment

There are couple of preparation steps you must take to create your development environment. I am using CentOS 7 as my development machine so I will use that system to describe everything, but it should be pretty straightforward to adapt the article to Fedora.

We first need the source code for the ovirt-engine itself. You can get it from the project's code review tool: gerrit.ovirt.org. Just execute the following command and wait for it to finish:

# git clone git://gerrit.ovirt.org/ovirt-engine.git

You will also need a directory for the development deployments, so create a directory somewhere. Mine is in ~/Applications/ovirt-engine-prefix. I have set the$OVIRT_PREFIX environment variable to point to that path, so when you see it used throughout this article, substitute the path for your own Continue reading
