I'm working on a filesystem improving project, and found a paper says the cheating on benchmark, and it gives a solution that use VMs could help others to reproduce our result.

And the question is, if I have made a specific vmware virtual machine, will it runs the same at different computer and platform?

For example, I have a virtual machine which is 1G RAM, 4G HD and 2G one-core CPU.

Will that runs the same at a qual-core 3G CPU and a 2.4G P4?

What if the computer have 4G RAM? Will vmware use some buffer mechanism to improve performance? If that's true, does it means the VM runs on a 2G RAM host will slower than on a 4G host?

Hope you can help me on that, or just told me where could I find the answer.
