Enable configuring mirrors from a file -------------------------------------- Key: OVIRT-1413 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1413 Project: oVirt - virtualization made easy Issue Type: New Feature Components: oVirt CI Reporter: Barak Korren Assignee: Barak Korren Labels: mirrors Right now mirror configuration can only come from a JSON file stored on the mirrors server. We want to enable taking the configuration from a local file also, this will enable jobs to manipulate mirror information before running the mirror injection process. This would be especially useful for change queue test jobs in order to enable fine-grained control over the mirrors being tested.
