add logs under /tmp to our job artifacts ---------------------------------------- Key: OVIRT-1764 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1764 Project: oVirt - virtualization made easy Issue Type: Bug Reporter: Dafna Ron Assignee: infra when engine fails to deploy it does not save anything in the regular engine log. however, there is a copy saved under /tmp which would make debugging engine failure to deploy issues easier to debug. Didi suggested that it would be a good idea to add the logs under /tmp to the jenkins artifacts job logs to allow easier debugging when engine fails to deploy.
