Are you using files or direct partitions for the guest image?  What
backend driver?

We are using files. What do you mean for backend driver?
BTW, we repeated those benchmarks with different installations, and it
seems that disk writes are really slow on OracleVM only.
SUSE Entreprise+Xen, as well as VmWare+Ubuntu have reasonable performances.
