vmware comes to mind (it's just been in the shoutbox minutes ago, that's why). although it may be a tricky (read: painful and troublesome) one to setup. you may have to google for step-by-step instructions on using vmware to virtualize vista, or seek help on their community forum.

you may also want to try microsoft's virtual server 2005 R2 (ssshhh, it's free), to see if it can do what you want:

Bochs why generally used for programming can emulate any x86 software. You'll need an image of a disk with Mac OSX on it. Bochs is easy to use and comes with settings that are good for most users as the default. I don't know an actual site, google bochs

You can try VirtualBox. Seems to be capable of emulating most popular operating systems, and it's free. It can also be runned on Linux.

and, is there a virtualization software that runs on xp and emulates Mac osx?

Unless you find some hacked up or beta version of Mac OS X (designed for the Intel platform), it is not possible to run that OS on anything but Apple hardware. The company put checks in to make sure it runs only on their computers.

 

As mentioned above, your choices for XP and Vista are VMWare, and various Microsoft products (like the new and free Virtual PC 2007, https://support.microsoft.com/en-us/products/windows).
