Hi guys, is there a way to have CPU queues go down when having a java app on a ovirt hosT ?

we have a idm app where the cpu queue is constantly 2-3 when we are doing things with the configuration but on esx on a similar host it is much faster

Your question is not clear to me and lacks a lot of details. I think what you are asking is 'why is application X running faster on ESX?' - am I reading it right?

Please provide much needed background information. What version of oVirt and hosts you are using, the configuration of the VM, the type of workload (IO bound? CPU bound? etc.).

Is that a Windows (based on the terminology 'CPU queues') or Linux VM? If it's Windows, have you installed all relevant virtio drivers? Is your workload using some kind of random data, perhaps (and then virtio-rng is quite useful to have)? etc.
