1)As i said, most kernel optimizations are already there, since host's kernel is 2.6.35. It's the host's kernel that is managing the metal, not the guest's. These tests do not show for example the difference of having a host with 2.6.12 kernel and having a host with 2.6.35 kernel.
2)The userland is too old(since from what i read you used Fedora 4 with all the kernels). For example the graphic stack should be vastly improved. Libraries are old etc.
3) While VM's are important for businesses. and what you have tested is indeed a usual use case senario, this senario doesn't correctly discribe kernel's evolution in general. What this article says is that it tries to measure kernel's performance through time, in *general*. It should be on real hardware, and if possible using appropriate userspace software for each kernel. I recognize this is difficult and time consuming, but it is the right way to do it.
