Hello Community,
after upgrading one node from 5.1.to 5.3 in a 5 node cluster, I can't do live migration of VMs. Now I'm stuck and in a bad situation, because I want to do a node by node upgrade of the cluster and I can't get the other nodes free...
Here is the migration log of migration from 5.1 to 5.3 node

Code: 
2019-03-13 14:03:50 use dedicated network address for sending migration traffic (x.x.x.x)

The machine is migrated, but in off state.

The machine is not migrated, still running.

Any help and suggestions are welcome.

but different mainboard manufactors (Intel/Supermicro)...

if they contain different microcode updates, this may very well be the problem, can you try with a test vm with another cpu type, e.g. kvm64 (ideally is it otherwise identical to your real vm)
 
kvm64 works... :eek:

All (>200) VMs have got the cpu type set to host.

Does this mean, the only option I've got is to alter the CPU type on every machine and do a stop/start cycle?

you can try to fully upgrade the bios/firmware of all mainboards, but yes to migrate them away initally, there is not really another way i am afraid
but an alternative to using the gui is using the cli tools (e.g. pvesh /qm) to change the cpu type and star stopping them
