I am running oVIRT 3.5.6 right now on Dell Blade Chassis, each oVIRT node has 2 x 10 core processors, showing 40 VCPU cause of hyper-threading. We are trying to figure out for a very log intensive application that requires lots of specs what the optimal configuration would be to allow it to use utilize all cores on the blade?  Is there advise on this? Like should we disable hyperthreading? What's the general rule of thumb?
