Multiple Mac OSx Versions on Same Mac - Snow Leopard & Lion

I'm wondering if it is possible to install different MAC OS versions (for example, having Snow Leopard and Lion OS X) on the same computer, as you usually do with different versions of Windows just making some partitions.

Is it possible? If yes, how?
I have to make sure that there will be no data loss.

    yes you can install both versions of Mac OSX.Make sure to take backup of your existing version which has been istalled.

    I think it's quite possible by creating virtual machines. Never tried it though.

    But the real question is whether you can install and run any version of
    OSX in a virtual machine that's hosted by non-Apple hardware.

    Apple's answer is (paraphrasing): ABSOLUTELY NOT!

    Even if you pay full price for OSX from a licensed Apple dealer, Apple thinks
    they get to decide what you can do with it. Some of us think it's unethical
    for the seller to dictate to the buyer, so I'm all in favor of any innovation
    that enables running it in KVM or VirtualBox on a Linux PC. And I've read
    that it's been done, but I haven't gotten around to it myself.

    Well, I've no clue how to partition a mac; and have no intention to partition my new 27". Lion just works very well. What I know for sure is that a Mac can run Windows 7 but not 100% sure about Lion & Leopard running on two partitions.

    Never read Apple's OSX License; but I've a solid reason to believe what you're saying. Does the license prevent us from creating a virtual OS on a Mac hardware and then install another version of OSX, say Leopard? They should have no problems with that.
