VMWare is on version 6. I was using it around 2001 to stop me having to have a gazillion PCs with different setups to test my stuff on. Do keep up old chap.

Have a look at zVM 5.3 which has just been announced, you can run thousands of zLinux guests (I know someone who has run 20,000+ zLinux images under zVM.)

There's also Xen for Linux - http://www.cl.cam.ac.uk/research/srg/netos/xen/ - which runs in the same way as the VMs do on zOS, i.e. at the OS level rather than in user space.

I worked for the biggest car manufacturer in the world and they used clustered VM's for their production environment.

So can you run Windows on Linux on Windows on Linux etc.?

I've only seen VMware used to run virtual machines side by side on the same physical machine.

Are you saying that VMware also runs one VM inside another, and if so how common is this?

MS Virtual Server is much better the Virtual PC but still nowhere near VMWare's offering.

Probably because out of the big three (VMWare, Parallels and Virtual PC) the MS offering is by far the worst performer. I wouldn't recommend it. This is because originally it WAS an emulation of x86 running on PowerPC. I suspect that some of that emulation is still buried in there.

It's also been crippled by MS from what it once was. Originally it was a Mac product and MS bought it, removed the ability for it to run on a Mac host along with a whole bunch of other features that were Mac specific, then released their bastardised version on to the world.

Basically MS saw the VM world running away without them so they bought the only product that would sell to them and then made it worse in typical MS fashion.

It is 100% a real test. Nothing is emulated here, you are running the real OS on a real PC (yours). VMWare (or any of the others) just provides a layer in-between to allow the guest OS to boot in it's own process.

Yep thats the idea, Linux, Windows, Solaris, Open/Net/FreeBSD, DOS, Netscape, etc

Now that VM-Player is free (you can only 'play' VMs not create them) there is a growing community around VM Appliances . So images of OS's tuned to a specific purpose, so you can have one for a particular mailserver, or security appliance etc.

And for the server, Microsoft Virtual Server 2005 R2.Which is FREE as well. That's right free.
