I have been wanting to install Linux on my Windows laptop for a while, but I did not want to partition for a dual-boot system. I have that on my desktop already. One of the Yahoo forums mentioned this software (which is free) and I decided to try it.
I installed SuSE OpenLinux on my Windows Vista laptop using the VirtualBox. It seems to work fine, with a few caveats. The Linux software,downloads and updates work fine. I have not been able to access my USB external hard drive yet. I need to read the manual to be able to switch my bluetooth mouse back to Vista as the process is not intuitive. Overall, I'm happy with VirtualBox.
Many times in this forum I've seen people unhappy with xyz OS or complained that the computer that they bought came with an OS installed. With VirtualBox, You can install several different OS and use the one that works best for your software. I may install Windows XP next so that my Meade software works again.
Regards,
Charlie B

Very stable system put together by Sun. I put it on my parent's Ubuntu system and have it running XP for any programs that don't work on linux. Does a nice job of managing system resources. There occasionally can be some goofiness with trying to access usb devices. USB drives have some issues being recognized, make sure they aren't mounted in your native operating system when you first plug them in. Also there should be in the lower right of virtual box an option to turn on and off all usb devices. Try flipping that on and off and the device should then load!

I'll be looking into this as well... wine doesn't like a lot of the astrophotography software (or rather I'm deficient in my manipulation of wine) and I'd love to be able to shell XP for them.

Can't get Windows XP to see my USB dongle. Seems there is a bug with the rights somewhere in the OS so I may go to bootcamp to solve this.
USB mouse works even though the virtual box says no USB devices are attached. Odd.
Video works pretty good but nvidia says I don't have a nvidia device - guess the virtual box causes that.

That's been a long standing beef of mine with virtualization. I'd love to run some gamnes in an XP shell, but a lot of DX stuff just won't run.

I've been using vmware heavily for quite a few years to do the same thing. Virtualisation is seriously great. These days I have a mac, with XP and linux running in virtual machines, all my needs are covered.
Some stuff I've discovered along the way:
- Most of the virtual PC's hardware is "pretend" hardware. It won't have the same hardware that you actually have - e.g. my vmware box says I have an AMD net card, when it's really an intel one. And the video card is a "VMWare SVGA II", instead of the ATI Radeon. What this means is that installing windows/linux/whatever is easy, as the VM software supplies drivers for its virtual hardware, but you lose a lot of hardware features.
- 3d/games/etc are hit and miss. The "paid" packages like vmware and parallels do have some 3d support, and a lot of games do run. But it's generally the older games that are supported, the latest and greatest either won't run or will run very slowly. The cheaper/free packages often just have basic 2d support.
- You can run lots of VMs at the same time, so long as they're not too busy and you have enough RAM. Here at work, I'm running 2 VMs with XP, 512MB of memory and a single CPU core each. They run fine generally, only getting slow if say I boot both at once so they're fighting for hard disk access. I have a dual core CPU with 4GB RAM.
- VM boxed have the best feature ever invented on a computer: a real 'Undo' button. I test lots of software at work... when it goes wrong, I hit the "revert to snapshot" button, and in a second or so I have a fresh, working install

Could not get the snapshot to work in Virtual Box - a very useful feature for sure.
I may have to look at VMware again. Got burned with it a couple times on Windows (lost my entire hard drive when W2K was the host - not a fun day).

I ran VMware on my mac, but eventually opted to go with the dualboot. XP was nice and fast, but the graphics were lacking. If you can get trial versions of the virtualizer program (cant remember if vm has such a trial), do try them out first. On another machine, VMWare refused to acknowledge my cd drive. 
They all have their little quarks, usb devices seem to make up the bulk of issues.

Before proceeding, how invasive is this VM host? On the same level as VMWare? (which is OK)
thanks in advance

What do you mean by invasive? 
What is the host OS you are thinking of using?

I mean removable from Windows XP COMPLETELY without any fuss. I would be running SuSE 11.x and Solaris 10 x86 in the VM.

Good question. With Windows you have that darn registary and it's hard to say if an uninstall will remove all the bits in there. Too many programs don't do that.
I'm using it in OSX so a removal is as simple as trashing the application. Same goes for Linux.
You make a good point, it's one of the things about Windows that really bugs me - removal is not as straight forward as it should be or could be.

I set up a user running VMWare on Linux with Windows VMs - in full screen mode the graphics were indistinguishable from "reality". The VM was so real it was - real.

Well I'm pretty d____d impressed! Didn't even have to restart Windows - I'm gonna call this "FreeMWare"  I have a second hard disk with a standalone SuSE 11.x install - we'll see if I can run it directly from a Windows VM - setting this up under VMWare was always a pain..

I switched to Bootcamp - easier than trying to debug the USB rights issue for the vitual machines. But it was pretty darn slick.
Keep us posted on what you think.

According to a good friend of mine (Senior Software Engineer) tells me Vbox and VM ware is used for R&D plus testing typically in the Linux environment ...

Yeah, virtual machines are used very widely for development. Here's roughly why:
- You just have one PC for development
- You have a bunch of VMs with different OS/software combinations. This replaces the room full of PCs you used to have with the same range of OS/software.
- You test your code out regularly. After, you want a clean install so you can test a fresh installation of your app. You just hit the big "revert to snapshot" button, and it's clean in 2 seconds. Before, you had to get your imaging CD out and spent 30 minutes doing this.
- You want to test for a bug. This means installing the app, spending hours getting it to the right state before you can start. At this point, you hit the "new snapshot" button, so you can test and then put it back to that "just ready" state. Before, you had to format the disk and start from scratch each time.
Just those few examples show how your productivity can go up by maybe 1000% when you're doing testing. This is why we love it so much

THe import of this is interesting - it means they can map ring 0 processes onto ring 1 for the x86 architecture, while handling the inevitable exceptions. Since this is a VM, it's not bound to time in the processor sense - so you can scan ahead for coming changes and intervene.
