Hi All, In the last days HE 4.1 suite is failing with the following error: *RequestError:* status: 409 reason: Conflict detail: Cannot migrate MACs to another MAC pool, because that action would create duplicates in target MAC pool, which are not allowed. Problematic MACs are 54:52:c0:a8:c 8:63 The MAC above belongs to the HE VM. HE-master works fine. Can you please take a look? *Link to Job:* http://jenkins.ovirt.org/job/ovirt-system-tests_he-basic-suite-4.1/ *Link to all logs*: http://jenkins.ovirt.org/job/ovirt-system-tests_he-basic-suite-4.1/42/art... -- *GAL bEN HAIM* RHV DEVOPS
