i just upgraded my cluster from ovirt 3.5 to 3.6. My ovirt nodes run centos 7.2.
I've got a problem about some guest (centos 6.x), when i try to run them i get this error:

"org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-41) [] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VM XXXXX is down with error. Exit message: internal error: process exited while connecting to monitor: 2016-01-05T12:02:56.879292Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15"

Looking forward in the log i find this : 
"2016-01-05T12:02:56.879615Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config
2016-01-05T12:02:56.897747Z qemu-kvm: "-memory 'slots|maxmem'" is not supported by: rhel6.5.0"

In RHEL KB i found this bug which seems to be the same that mine :  https://bugzilla.redhat.com/show_bug.cgi?id=1275268


So my question:
- is it really problem of "memory hotplug" if yes how can i disable it?
- My guests seems to inherit of parameter "Custom Emulated Machine" with value rhel6.5.0 from cluster config but i did not see how to modify it?
