Hello,
my suspect was correct.
I found some reference here about possible values:
http://www.ovirt.org/Features/Detailed_NUMA_and_Virtual_NUMA
so I made this
[root@ovirtmgr ~]# cat numa_tune.xml
<vm><numa_tune_mode>interleave</numa_tune_mode></vm>
[root@ovirtmgr ~]# curl --insecure -u "admin@internal:my_password" -H
"Content-type: application/xml" -T numa_tune.xml '
https://ovirtmgr/api/vms/168470b1-b7eb-4dab-8fa4-6b744e2ad738'
and now start of VM succeeds with
[root@ovirtmgr ~]# curl --insecure --request POST -H "Content-type:
application/xml" -u "admin@internal:my_password" --header "Accept:
application/xml" --data '<action> </action>' "
https://ovirtmgr/ovirt-engine/api/vms/168470b1-b7eb-4dab-8fa4-6b744e2ad73...
"
In qemu log file for the VM

The question now is how can I influence configuration from the GUI so that
all my VMs are by default created as interleave.
I will also try to create VM from scratch in 3.5rc3 to find if the problem
could arise only for pre-existing VMs or not...
Comments welcome on my findings....
