vGPU becomes very inefficient when I use it in ovirt instead of qemu-kvm
We distribute vGpu in order to use it in virtual machines. I find the same type vGpu get differently performance in Ovirt and Qemu-kvm . when I distribute a vGPU to Ovirt virtual machine,it's performance becomes very strange.Some games can run efficiently and attach 200+ fps.However,in some other games,it's can't even attach 10 FPS. But in Qemu-kvm,the vGpu's performance always efficiently,can run these games all in 200+fps. I've been stuck with this for weeks and I have to make it always runs efficiently. Can someone help me?Thank you very very very much....
In above, the "qemu-kvm" means I directly construct a virtual machine by virt-manager in server

Sorry, not without the logs or more details… Can you describe it more concretely what you are doing exactly in virt-manager vs ovirt? Thanks, michal
