I have an ovirt cluster running ovirt 4.0 and I am seeing several errors when I attempt to put one of our nodes into maintenance mode. The logs on the source server show errors as follows. Feb 23 10:15:08 ovirt-node-production3.example.com libvirtd[18800]: operation aborted: migration job: canceled by client Feb 23 10:15:08 ovirt-node-production3.example.com libvirtd[18800]: internal error: qemu unexpectedly closed the monitor: 2017-02-23T15:12:58.289459Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: 2 3 4 5 6 7 8 9 10 11 12 13 14 15 2017-02-23T15:12:58.289684Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config 2017-02-23T15:15:07.889891Z qemu-kvm: Unknown combination of migration flags: 0 2017-02-23T15:15:07.890821Z qemu-kvm: error while loading state section id 2(ram) 2017-02-23T15:15:07.892357Z qemu-kvm: load of migration failed: Invalid argument This cluster does *not* have NUMA enabled so I am not sure why this error is happening. Some migrations did succeed after being restarted on a different host however I have two VMs that appear to be stuck. Is there a way to resolve this?
