OS Switcher?

[KitchiRUs]

Hi,

I'm running 3 OSes on my computer, for a variety of reasons. And I tend to switch between them on average about once a day. Booting into one and then into the other, I think we can all agree, is a solid pain in the ***.

I was wondering if there was a way two "switch" between operating systems, which made things easier than rebooting everytime. Kind of like suspend the state of one, and switch to the other without a reboot?

Like a alt-tab on steroids, so to speak.

If the OS are all (the same) Linux, and are just diffrent with their DE, you could achieve this.
Other than that, no way.

What is a DE?

I may sound like a complete jackass here - but there is no way one can write low-level code to 'support' different OSes? Say different varieties of linux, if not Linux and Windows?

I'm talking about something that will converse with the Linux low-level code, and converse with the hardware. So when one switches OS versions, the 'interpreter' just interprets for a different OS, and the system doesn't have to reboot.

Try running your different operating systems in virtual machines. You boot your "host" operating system, start your virtual machines that run the different operating systems you need. You can be running Windows, Linux, etc... all at the same time on one computer, and you can switch back and forth as easily as switching to a different window.

Look at KVM/qemu or virtualbox

So I have looked at VirtualBox. The only problem for me is that I use Ubuntu for gaming, and Fedora for some reasonably intensive programming. That runs terribly on VMs. :P

This is more of wishful thinking from my part rather than actually looking for solutions.
