[solved][very solved]Is testing an OS in virtualbox realistic for compatitility?

Post by oldgranola » Sun Jun 10, 2018 12:15 pm

Very basic question that I don't quite find the answer. Having fun firing up virtualbox on LM17 cinnamon and playing with beta LM19 and MX-17 (really liking that one!). They work albeit a tad slowly probably due to needing to allocate more resources to the VM. Other than that, is testing an OS in a VM a realistic test of the OS's compatibility with my hardware? Doesn't the VM provide functional environment for the guest OS? If the particular kernel the guest OS would use is problematic for the host machine if installed and run by itself, would I see that while running it as guest in a VM? Would a live USB test be more 'realistic'? I have read of instances where things work from a live usb but not so well once locally installed

Thanks!

You can't test hardware compatibility in a VM.

If everything works after booting from a live DVD/USB then the chances are that its going to work just fine after you've installed, be sure you check all your devices and wifi before proceeding.

The most common problem is a 'black screen' which can be fixed with nomodeset in grub... so read up on that one first too.

Virtual machines "fake" common hardware that should work with any operating system. The guest OS doesn't get to see the real hardware at all (and doesn't know it). But running the OS "live" from the DVD or USB stick is a good way to test with the real hardware.
