The disk I/O performance of a para-virtual machine was found to be comparable to the real one. The overhead of the virtualization on the computational performance was as low as 5 ～ 15 %, depending on the type of applications. On the other hand, the MPI communication throughput measured at 16 nodes was a half of the real machines, at best.
