Hello. I tried to reinstall my whole environment using oficial oVirt ISO image and the same problem occurs. I also tried to give full access to vdsm user in sudoers file and the results are exactly the same. This is the error on showed on oVirt Manager: VDSM command AttachStorageDomainVDS failed: Cannot obtain lock: u"id=e65b4f0f-faa1-4cdc-9d2a-ab4fccfec0b0, rc=1, out=[], err=['setsid: failed to execute /usr/bin/ionice: Permission denied']" In other hand, the node server's vdsm.log file shows no errors. The engine.log still shows the same errors as my previous posts with logs. I don't know what else can I do. Please help.
