How to run your own computer as an internal virtual machine?

Question

linux

Is it already possible to run your own computer in a virtual machine? For example, on Linux, run your own computer as a virtual machine?
Well, or a system that can keep several operating systems running at the same time and switch, say, between them, as if between desktops?
If possible, please tell me by what means?

Answer 1

You can't do without making copies.
You can capture a system image and run it in a virtual machine. Or install (clone) systems on different disks and connect these disks to a virtual machine.
But the hardware configuration for a system running in a virtual machine will differ from the real one.

Answer 2

use P2V

If you have a modern Windows (7+), then yes. Vbox can link physical partitions and run a virtual machine from them.
It will not work with XP - it will fall into the bsod because of the drivers and "what did you change such a bunch of iron for me here ???".
