I am not sure if this is true. Well, you are not really making a statement that could be easily interpreted. Virtio is specifically created to address performance issues with virtualization. Are you unhappy about the implementation quality or you generally believe that para-virtualization is not the way to go about improving virtualization overhead? One prime example when with virtio it was possible to get native performance _after_ minimum configuration tuning: https://serverfault.com/questions/407842/incredibly-low-kvm-disk-performance-qcow2-disk-files-virtio https://serverfault.com/questions/407842/incredibly-low-kvm-...
