Remember a process get's a virtual memory image, as if it's the only process on the machine.

I'm sorry but I'm still not clear about the idea. Could you please explain a little more?

And one more thing is that when I do it on a VM that runs Mandrake Linux with an older kernel it gives me a constant address.

Virtual memory - each process gets a completely new address space from top to bottom, program gets loaded at the bottom.

Next time program gets run, it gets a completely new address space from top to bottom, program gets loaded at the bottom.

That means the virtual address, say 20000000 to keep things simple, for each process gets mapped to a different physical address by the OS.

process 2416 address 20000000 = real address 0x23456666
process 2082 address 20000000 = real address 0x12347777
