Is virtualization worth it?

Post by code65536 » Sat May 26, 2007 9:20 pm

A lot of the "consumer" Intel chips have VT stripped out of them. Only the upper-mainstream and higher level chips like the E6xxx series have VT. I don't need the extra power that the higher-end chips offer, so the only benefit (for me) of a higher-end chip is VT.

So for people who have used VT, in your opinion, is it worth it? Does the hardware VT acceleration make a noticeable difference?

BTW, I use VPC2K7...

(I figured that with all the people testing Windows installs, I have a better chance of finding someone with experience playing with virtualization here :))

off topic but are you the same code65536 from http://club.cdfreaks.com/?

If so welcome to our humble abode.

On-topic I'm not clear on what you were talking about. I guess I need to google some more. :)

Yes, and thank you... :) though I've given up my moderatorship there and have been retired from the ODD world for nearly two years now.

"Vanderpool" is an extension of the CPU's instruction set--analogous to how MMX and SSE are extensions of the instruction set--designed to accelerate virtualization by implementing in hardware some of the overhead needed for virtualization. In theory, it's supposed to reduce the performance delta between live machines and virtualized machines, but I don't know if that improvement is significant enough to be worth the price difference between Intel's budget and performance chips or even to be noticed.
