Do you drive a car? that's another OS.
Phone? Another OS.
How about your TV? That runs Linux. (Yes it really does, look at your manual.)

If you are a windows user, that is 4 for every person that owns a car and a LCD or Plasma TV.

I ride a Motorcycle and have 3 cars, so I interact with 7 Operating Systems every day.

Oops, forgot that the Copier here at work Runs QNX, That's 8.

That you Canadians are doing what the United States is telling you to do.

Good lap dog!

And yes, I am trying to enrage you, why are you people not fighting the corruption that is bleeding over the border from our country? The more you just let this stuff happen, the more they will try and roll over you.

Starting with a lot of Congress being tried for Treason against the People OF the United states, those found guilty need to face a firing squad and have it televised on C-SPAN.

Problem is the sheep in this country keep voting for these scumbags that want to hide everything so they can try and get away with more.

The busy little beavers who track bills now include committee hearings. For example, here's some of the debate on the Copyright Act, C-11

Oh Yay, more bad Sci-Fi with Kevin Sorbo....

Why cant they let that whole show just die?

Whether or not you virtualize a given workload, you need to manage its resource usage. In the trivial case, you can see your CPU used up by some other program unless you provide your program a guarantee of enough CPU for the actual number of users who will be employing it.

Ditto memory, disk and networ I/O, bus bandwidth, etc, etc.

A more surprising case is putting two workloads together that formerly worked properly on an older, slower machine. If you increase the amount of a critical resource, both programs under load will start using more of every resource. For example, a batch job that got 30% more CPU increased the amount of disk I/O it did by several times. An interactive program on the same machine was rendered almost completely unusable because it couldn't do the I/O it needed. The customer in that case thought the vendor was lying about the speed of the machine, and demanded his old one back.

Linux is a hotbed of resource management experimentation, so you can statically size and configure a program (workload) to be able to withstand a given load. Commercial Unixes have good enough controls to do most common cases. I can't speak about Windows and BSD, as I've not researched them (yet). Mainframes, not surprisingly, have the best controls for what in their days were exceedingly precious resources.

If your OS doesn't have good resource controls, or if you don't know how to use them well, you'll end up splitting up the virtual machines onto a undesirably large number of physical machines, just in order to do the management the hard way.

The difficulty, by the way, varies as something like the square of the number of machines and the resources used, so virtualization and consolidation is easy for well-behaved, small and unimportant programs, and can be evil for anything that turns out to be big, resource-intensive or important. Think of that as a lemma used to derive Murphy's law (:-)).

You seem to not be able to read or figure it out, so I'll explain it to you..

I by used and therefore I AM A DIRTY THIEF. I suggest you read again and brush up on your troll skills, you suck at it.

The Used game market is huge, and a MAJORITY of players rely on or use the used market like EB games regularly. I know it pisses off the game makers that us "dirty rotten thieves"(tm) are stealing their money by buying and playing a used game. But most gamers do not buy into their delusion and prefer the lower prices of used games and the ability to sell games for a store credit.

I know I'll stop buying games if I cant buy a disc that I can then later sell used, or buy a older game used.

I never played any of the bioshock games, so I picked up I and II for $9.00 and enjoyed the low cost entertainment. I am actually thinking of trying borderlands next.

I would never have bought any of them at full rape me retail price of $60.00 each.

Zombies.

"Who is the government?

We the people."

Where do you live? Because I'm from the USA and it has not been "WE the People" for as long as I have been alive. WE don't even vote for our own president, we vote for someone who we hope will vote for our choice in president.

And sorry, but the Poor and middle class outnumber the 1% by 99% yet almost everything is DICTATED To us by the 1%.

So I would love to live in your country of "We the people" because it's not found on the american continent.
