Hi, I read reports about the bug I opened : https://bugzilla.redhat.com/show_bug.cgi?id=1543833 and I have just updated all my infrastructure. But the problem is still there unfortunately : 2018-04-04 17:05:17,470+0200 INFO (vm/1658d6ce) [vds] prepared volume path:

Regards
If that VM was incorrect before the problemativ device is already there. Try switching off virtio-scsi, run, turn it on again. Disable iothreads too. Give it a try, but it may be that a db update to drop that device is needed eventually.
Yes, this VM was incorrect before. If I disable both virtio-scsi and iothreads, it can start. With only iothreads, it can start too. But if I also enable virtio-scsi, it fails. Could you explain me what to modify in the database ?
I think I have found the required workaround that allows a VM with conflicting settings to be cured : - In the "vm_static" table, find the "vm_guid" related to the known "vm_name" - In the "vm_device" table, locate all "controller" devices related to this VM (vm_id = 'VM_GUID_FROM_PREVIOUS_STEP' AND type ='controller') - There will be a "device" record whose "value" is "scsi" : delete it Then I was able to configure all disks as "VirtIO-SCSI" devices again, using IO Threads, and the VM started flawlessly
should be fixed by bug 1535961 *** This bug has been marked as a duplicate of bug 1535961 ***
