Based knowledge of the architecture of paravirt/ fullyvirt I/O subsystems, there is no way in the world fullyvirt will ever outperform paravirt for network or disk. In previous benchmarks I've typically seen Paravirt have x2 the disk performance of fullyvirt, and have x10 the network performance. I'm not familiar with UnixBench enough to say whether it is good benchmark to use, or whether these were just runtime anomolies. I'd recommend doing some disk I/O tests using IOZone which is the pretty common standard for disk benchmarking. I'd also recommend doing some scaling tests using multiple concurrent guests, since people rarely use virtualization for just a single guest. When adding additional concurrently executing guests I'd expect to see the gap between paravirt and full-virt increase even further.
