Bonnie++ and Xen

I ran some filesystem tests with bonnie++ on a DomN, Dom0, and the machine that is exporting the lun over iscsi. The results can be found here. Looks like there is some significant impact from using Xen on older cpu's without the extra virtualization goodies. I suspected this would be the case but now I have some hard numbers.
