Mac OS X Lion capable of running multiple virtual copies

updated 06:55 pm EDT, Fri July 1, 2011

Virtualization previously limited to Server

Apple has reportedly modified its end-user license agreement (EULA) to enable Mac OS X Lion users to run multiple copies of the operating system on one machine. The new EULA, distributed alongside the Lion Golden Master build, is said to explicitly allow users to run up to two additional virtual copies of the operating system, without requiring additional licenses for each virtual machine.

Mac OS X Leopard first brought the ability to run virtual machines, however the feature was limited to the server edition, according to a MacRumors report. Users also had to obtain a separate license for each of the virtual machines.

Aside from the new virtualization capabilities, a separate report suggests Apple may be eliminating the welcome video for Lion. In the GM build, which has included the video in the past, users are no longer greeted with "Welcome" presented on the screen in different languages while a song plays in the background. Instead, new installs are said to transition directly to the setup assistant with an introduction to multi-tough features.

    Good ridance..

    I never liked the welcome message. Just wanted to go straight in and start setting up stuff.

    Forgive my ignorance

    What would be the need for running 2 copies on 1 machine?

    you need to run Lion in order to install Server. This is about Server more than about Lion.

    On the one hand...

    My initial reaction was "I can finally virtualize the OS! Hooray!"

    And then I thought about it -- the main reason to virtualize the OS, unless you're running a separate OS entirely (like Windows on Mac or Linux on Windows) is because you're doing something which is likely to bring down the OS and you don't want the machine to actually crash. It has been a very, very long time since I had a Mac crash, so maybe this feature won't be so spectacular after all.

    Then again, I could create a virtual machine for the various badly-written programs which don't function properly if you aren't logged in as an administrator (Adobe, mostly)...

    OS virtualization

    The reason to virtualize is to be able to run totally separate instances of an OS with applications so they don't conflict with each other. It can also be used when testing different configurations. The benefit of virtualization is the ability to run these instances on one piece of hardware, maximizing your hardware investment. Problem is Apple doesn't sell a real server product and unless things have changed, you'll still have to run all instances of OSX on Mac hardware. Virtualization really come in with server clusters where you can automatically switch the VM-OS to a different CPU(s) to maximize throughput. Mac clusters can be configured but not as easily as Linux clusters.

    For the general public, virtualization isn't something you'll want to worry about.

    prl99 offers the best reason. The primary purpose of running the same OS in a VM is to be able to test different configs. I would think this would be possibly helpful to developers but it would make more sense if we could run different versions of the OS X in VMs under Lion.

    ..."Multi-tough features"?

    Wow, that sounds like one muscular upgrade! (Or perhaps a typo.)
