So in config 1 you put the benchmark in different domU?

To narrow down possible problems, I suggest you put it in the same
domU first, so the config will be identical to bare metal. Also make
sure that both bare metal and the domU are running from the same block
device (kinda tricky, but possible if you use UUID or LABEL).
