Say all you want about multi-boot or virtualization. Both great options in many cases... but I'll stick with multiple computers for testing. Okay, beat me - I'm old school. But a Pentium 2 with 512 ram is what some people still use at home or in offices and I want to genuinely see my stuff run on the real world machines that the customers use. Or a box that *doesn't* have my choice of multi-head video card. Or as someone else pointed out, a different set of installed applications that may not play well together.

I hit upon the most ingenious new business. One which we all can identify with, and thus, should pool our awsome resources and develop as a national - nay - International Icon.
"CUPS" - A new coffee house. Service is provided by young and amazingly attractive wenches dressed in hot-pants or pleated micro-mini skirts (plaid), and tight T's (Tank-tops on special occasions).
Coffee comes in four standard cup sizes: A, B, C, and the thoroughly satisfying D cup!
For those with more exotic taste, there's the Latte - availble with a Double-D option.
Just a few more ideas and we're all rich - awake - and glad of it!

Why have dual or more boot with hard disk space partitioned for more os when you could have all os u want without restarting your machine???
i have only one os at boot (xp pro sp3) but with virtualization (i use virtual server 2005 rc2 sp1) i can have every os i need for testing
Indeed i have 4gb rams and one hd mainly dedicated for virtual machine hdd... 
the pool should be:
How many operating systems do you have on your development machine
checkbox: check if you use virtualization
radio: 1 only
radio: 2
radio: 3
radio: 4
radio: 5 or more

I had to say one only because I only have one bootable OS on my home development machine (gentoo linux) and one bootable OS (win XP) on my work development machine. However I do use virtualization on both when needed.

well, in my personal opinion, i like virtualization but in that way it doesn't take advantage of the real hardware, because it only uses a restricted set of drivers and generic hardware.
in order to really test or use an operating system i prefer install it instead of virtualization

you are right... 
i was referring to my situation... i usually develop application or web site that don't mind about hardware so i don't need to test them on real hardware.

I currently have one installed Operating System - Windows XP SP2, but also run DOS and Knoppix in Virtual PC. If OS does not fully support hardware, virtualization is better
I have also several small DOS-style OS (and bootable programs) I had written. Do they count?
One very interesting question: How many Operating Systems should have an OS development machine?

Well if we count that, I have memtest86 as a direct boot from grub so I guess that would count. Although since this has no files and only a single app I am not sure I can call it an os...

Pedantic much? Technically you don't boot more than one, but you know what the question meant, you don't have to be so pedantic...then again...this is a programming forum...

Hi
I use dual boat XP and window server 2003 and also two machines with remote access. Because on one machine we have Microsoft CRM and on an other one we have SQL Reporting Server and bla bla.
Why not Microsoft applications often conflict with each other ?

Guys was vista suppose to be a test program or what? I must admit that am impressed by half of its properties.

We have boxes in data centers in different states.
I've got a slackware linux server running which we use for remote code compiling.
But on my personal development machine its Windows 2003 (most of us are using that)

I used to be a huge believer in dual, triple and quadruple-booting...until virtualization came along. Nowadays multi-booting isn't worth the aggravation. I'm not going to stop whatever I'm doing, shut down and restart my system just to test my app's behavior under another OS (and then reverse the process to get back into my development environment). I've done way too much of that for years, and I'm not going back.
Nowadays, where virtualization is impractical, I'll just use another box. Multi-booting is just a huge interruption of my work flow.
I think a followup question would be, if you're not using virtualization already, why not?

Not all hardware runs virtualized enviroments well. I have a P4 2.6 GHz HT with 2 GBs of RAM, and while the machine is quite well performing (considering it's ~3 years old), I found that multi-boot is the best option so far: VMs are incredibly slow here.
I have XP, Vista and Ubuntu on different partitions, but I use XP for daily use - the other two os are for testing purposes.
Of course it adds its share of overhead, when reinstalling one of the systems for example, but it's easy to get used to fixboot and grub

...those would be the circumstances where I mentioned I'd use a separate physical machine. If I just need to do a quick test on, say, a plain Win2K box (which is something I'd never use otherwise) with no particular hardware requirement, a VM will serve my needs. I suppose it all depends on what it is you need to do while you've got those other OSes up and running.

I've run VMware and Virtual PC/Server on older hardware. Of course, yes, the virtual machines are slower than running natively, but whatever it is I need to test, I can still accomplish that faster than stopping my development environment, rebooting, doing my tests, rebooting again, and getting my development environment back in the state it was in. It would only get more painful to code/test/code/test if I had to reboot every single time. I'd rather put up with slower guest OSes.
If the host OS is starved for RAM, I can just suspend the VMs until I need them again--it's still faster to resume a VM than completely rebooting the physical machine. If that becomes too much of a pain, then I'll throw more RAM at the host; it'll pay for itself in no time.
Bottom line, my productivity as a developer can't be optimal if I spend half my time waiting for a machine to reboot. I've done it for so many years, I couldn't justify going down that route ever again.

I am a big fan of virtualization, but sometimes it just does not work. At my previous job, gdb would sometimes completelly freeze the VM. Eventually, I got a separate machine for Linux.

I'm completely with you. I wasn't claiming virtualization was the answer to everything. I'll get another machine long before I ever contemplate a multi-boot setup, however. I've gone through enough upgrades at this point that I've build more machines than I currently need.

I agree to an extent. It's hard to justify buying a new box for testing games or other hardware intensive apps for different OS's with the same hardware spec though. Say a game or other app needs to tested to run on a specific hardware set for 3 different OS's. It's impractical for any company or individual (that is not generating some immediate revenue) to say that it's more cost-efficient to save 3 minutes time lost from a reboot to reproduce a 2000$ gaming rig. In fact, it would be more practical in some cases, to have two versions of the same OS installed on one machine(each with a different vid card and driver set that it has been configured for) as long as you have relatively quick access to the guts of it), but that's all relative to your number of employess/salaries/budget. That said, i do most(if not all) of my managed development on a xp virt. machine in VPC 2007, but if I need some real hardware access and performance I'll reboot, although I do have more than one pc on a kvm if i really need to do something important in the 1-3 minute timeframe that it takes to reboot.
