Sorry Michal, this information is already gone - the versions on both hosts should have been identical - because thats why the machines migrated - I was running "update" from the ovengine UI on those hosts, But of course towards the end for the final host to be updated all the others (target) were already running the updated version. But of course this cannot be done in another way I guess ... Am Donnerstag, den 07.06.2018, 20:00 +0200 schrieb Michal Skrivanek:

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
this is typically due to using some unsupported version. Can you include the whole qemu log and versions from both source and destination hypervisors, and verify there were no updates run while that VM was running?
Thanks, michal
is there anything I can do about this? The hardware of all nodes is 100% identical
