Thanks for your query.but I didnt get the question proper.
R u worried abt the VT pros and cons ?and budget.? anyways i have attached NHM white paper ( may be useful)
please revert with the appropraite question for clear answers.
No, I would not say I was worried. Virtualization is exactly the trade-off you mention - it is less expensive on hardware, but you are putting all your servers into one infrastructure.
Was that your question? Or are you more looking for someone to tell you "Yes, you should implement this" or "No, you should not"?
