CQ first failure was for patch: https://gerrit.ovirt.org/#/c/98553/ - core: Add display="on" for mdevs, use nodisplay to override But I do not think this is the cause of failure. Adding Marcin, Milan and Dan as well as I think it may be netwrok related.

Evgheni and I confirmed this is not an infra issue and the problem is ssh connection to the internal vm Thanks, Dafna error: 2019-03-22 15:08:22.658+0000: 22068: warning : qemuDomainObjTaint:7521 : Domain id=3 name='vm0' uuid=a9443d02-e054-40bb-8ea3-ae346e2d02a7 is tainted: hook-script Why our vm is tainted? 2019-03-22 15:08:22.693+0000: 22068: error : virProcessRunInMountNamespace:1159 : internal error: child reported: unable to set security context 'system_u:object_r:virt_content_t:s0' on '/rhev/data-center/mnt/blockSD/91d97292-9ac3-4d77-a152-c7ea3250b065/images/e60dae48-ecc7-4171-8bfe-42bfc2190ffd/40243c76-a384-4497-8a2d-792a5e10d510': No such file or directory This should not happen, libvirt is not adding labels to files in /rhev/data-center. It is using using its own mount namespace and adding there the devices used by the VM. Since libvirt create the devices in its namespace it should not complain about missing paths in /rhev/data-center. I think we should file a libvirt bug for this. 2019-03-22 15:08:28.168+0000: 22070: error : qemuDomainAgentAvailable:9133 : Guest agent is not responding: QEMU guest agent is not connected 2019-03-22 15:08:58.193+0000: 22070: error : qemuDomainAgentAvailable:9133 : Guest agent is not responding: QEMU guest agent is not connected 2019-03-22 15:13:58.179+0000: 22071: error : qemuDomainAgentAvailable:9133 : Guest agent is not responding: QEMU guest agent is not connected Do we have guest agent in the test VMs?
