Hi, This was an old issue bug solved in 4.2.2, as you mentioned. The problem then was due to correlation failure with devices reported by vdsm. I suspect that this time it may re-occur because of alias name correlation failure, but not sure. 1. Did you run the VM with "run once" or a regular running operation? 2. Can you please send the vdsm.log and engine log from the time range of creating the VM till restarting the VM with a failure?

Hi all.
I'm testing oVirt (it's new to me also) and create some VM with nearly-all-default parameters. (ovirt 4.2.7, with last updates)
I create one disk for VM (via webui) : General -> create -> new image with default interface virtio-scsi (boot, 50 Gb size) resource allocation - virtio-scsi enabled by default IO threads enabled by default I run it with cdrom+iso for install centos.
When i try to reboot it this VM can start or not can start with error (one time start, next reboot - not start, sometimes after it start...)
[org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-3) [] EVENT_ID: VM_DOWN_ERROR(119), VM test_rh1 is down with error. Exit message: Ошибка XML: Обнаружено нескол ько контроллеров «scsi» с индексом «0».
(by the way , why errors are localised? it means "Multiple 'scsi' controllers with index '0'"
In engine log here is a config xml dump:
<controller type="scsi" index="0"> <address bus="0x00" domain="0x0000" function="0x0" slot="0x05" type="pci"/> </controller> <controller type="scsi" model="virtio-scsi" index="0"> <driver iothread="1"/> <alias name="ua-8d89c0be-523d-4e8f-8968-3658adcd6748"/> </controller>
It is really contain two controllers:
<controller type="scsi" index="0"> <controller type="scsi" model="virtio-scsi" index="0">
But I do NOT add two this controllers by hand! And sometimes it can start! (without configuration change)
So there is a Question: How to workaround this and start the VM? In "vm devices" I have two controllers:
virtio-scsi {ioThreadId=1} scsi {type=pci, slot=0x05, bus=0x00, domain=0x0000, function=0x0 {index=0}
But all checkboxes are greyed
