[JIRA] (OVIRT-2252) The s390x slave is used in parallel by both the staging and the production CI systems

The s390x slave is used in parallel by both the staging and the production CI systems ------------------------------------------------------------------------------------- Key: OVIRT-2252 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2252 Project: oVirt - virtualization made easy Issue Type: Bug Components: CI Mirrors Reporter: Barak Korren Assignee: infra One of the tests of the CI mirrors python package is starting up an HTTP server on a fixed port number. This can cause an issue if the same test is running in parallel on the same machine. This typically cannot be an issue on the CI infra because it never runs more then one STDCI thread at a time on a given slave. This issue does arise specifically on the s390x slave because there the same slave is used both by the staging and the production CI systems. In that case the two systems might be trying to run the same test at the same time, so this can lead to port allocation exceptions.
