by the way, since the same DomU image can get better results on another hardware machine, we first assume there are some interference from Dom-0. However, when I run the same program in Dom-0, the results looks very good, almost the same as native case, just a few out liars. Which means the interference form Dom-0 is not causing trouble for dom-0, but can interfere with cache program in Dom-U? Is this assumption valid?
The domain-0 I tried are: 1. Ubuntu 12.04.2, default 3.2 kernel 2. Ubuntu 12.04.2, self compiled 3.11 kernel 3. Ubuntu 12.04.4, default 3.8 kernel 4. CentOS 6.2, self compiled 3.13.6 kernel
