Description
Just an Idea. Maybe you could develop a program called SwitchOS which allows users to switch between different OS's seamlessly. For example, you could have Fedora, Ubuntu and Standard Linux on a PC. When you boot into Ubuntu (Which would share the software between the OS's) or any of the other ones there will be, on the programs menu under 'Utilities', SwitchOS. When you boot the software would, in the background, start all of the OS's so you can switch! Basically like your Desktop Switching but with OS's!
A Reply to Eldmannen's comment: Standard Linux is basically Red Hat and stuff like that! It is not lets say Fedora or Debian!

I always wanted that, but I don't think it's possible.
You'd need something like a tiny "VM-OS" which can boot different OSs including Ubuntu. But you would have all the VM disadvantages like slow speed.

Standard Linux?
Is that like Standard Oil?

Download the latest virtualbox .deb file and install such magnificent piece of software.
A normal program cannot switch OSes, an OS is like the software core, so the closest thing you can have to what you want is virtualization, which is already possible with things like virtual box and vmware.

Impossible to implement, illegal to support.

I tried to create an OS that would do this and I ran into lots of trouble (biggest being a lack of developers). What you need to do is have a VERY small OS (I was using a modified Minux OS) and have hardware "containers" attached to the OS that directly called on hardware the same way an OS does. When the main OS loads it will load the virtual environments and simultaneously load any other OSs. This drastically slows down the boot time for each additional OS you want to run. The end result though is you can use the super + tab hot key to switch between OSs. If you are willing to pick up the work I started that would be great but don't expect a lot of help until you have at least an alpha version of the OS.

Three possible ways:
1. Suspend to RAM/HDD and kexec()
2. Virtualization
3. Containers/Jails/Zones
Issues:
1. Basically dual booting.
2. Slow.
3. Can only run Linux as guests.
