Reproducibility of VM Servers

[Anup]

I wanted to get an assessment of reproducibility of a server environment set up in oracle VM. If I develop my code with the help of a linux server hosted on a local virtual box, can I expect nearly the same behavior when I push my developed end product to actual server running on the same os (ubuntu server) but on commercial machine instead of local virtualmachine?

What is the reproducibility of Oracle VB?

Kind of depends on what you are developing, but I would think the similarity would be the same in a VirtualBox guest as it would be on bare metal.
Look at it this way, You are installing a full blown OS so it isn't a emulator. There are some differences with the detected hardware, so that is where it gets dicey if you are writing device drivers.

Thanks Perry, but there you go thats my fear. I may be making kernel level finetuning to help sharpen my underlying services. If that kernel is taken out of incubator (Virtualbox) and kicked out into real word I dont want it to go bad.
