During update to 4.1.3 I moved the engine vm without problems to the already updated hosts. But I suppose during migration the qemu-kvm command line is preserverd, isn't it?

Frome where on shared storage are they read?

Possibly the problems is generated by my nested environment: L0 = ESXi 6.0 U2 on NUC6i5syh L1 are my oVirt hosts on this L0 L2 is my engine VM that doesn't start in 4.1.3 it seems that cpuType=Broadwell and/or emulatedMachine=pc-i440fx-rhel7.3.0 generates problems....

And I think I would have same problems with ordinary VMs, correct? Gianluca
