Upgrade to the latest oVirt - which provides support for the latest and greatest hypervisor features. 2. What is your bottleneck - CPU, storage, network, some of each? Many times, careful NUMA pinning is a good start - after you've ensured the rest is OK (use of virtio, enough RAM and CPU per VM, storage and network configurations, etc.). Also - some applications benefit from hyper-threading, some don't - experiment with both settings.
