[ovirt-users] guests crashing during live migration(NUMA config issue)

Hello, during updates of our physical nodes running ovirt 4.2.3 I had to live- migrate all VMs to evacuate them from the hosts. This caused roughly 10% of guests to end up crashed /shutdown after live migration. Errors in the Logs are: 2018-05-31T15:15:51.273805Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future 2018-05-31T15:16:54.596554Z qemu-kvm: Unknown combination of migration flags: 0 2018-05-31T15:16:54.597196Z qemu-kvm: error while loading state section id 3(ram) 2018-05-31T15:16:54.598491Z qemu-kvm: load of migration failed: Invalid argument 2018-05-31 15:16:55.010+0000: shutting down, reason=crashed is there anything I can do about this? The hardware of all nodes is 100% identical -- Andreas Balg
