My version of vdsm as stated by Dreyou: v 4.10.0-0.46 (.15), builded from b59c8430b2a511bcea3bc1a954eee4ca1c0f4861 (branch ovirt-3.1) I can't see that Ia241b09c96fa16441ba9421f61a2f9a417f0d978 was merged to 3.1 Branch? I applied that patch locally and restarted vdsmd but this does not change anything. Supported cpu is still as low as Conroe instead of Nehalem. Or is there more to do than patching libvirtvm.py?
