Switch between OS's without a hard reset 18.10 to 18.04?












0















I noticed we can switch kernels without a reboot, so I was wondering if I can switch between OS's without a hard reset, ie. killing all processes in my Ubuntu 18.10 to "BOOT" 18.04 kernel and file system which is in an another partition, without a hard reboot?



edit0: I want to switch between OS's that are in my hard disk. ie. while in Ubuntu 18.10 i would like to boot into another Distro without a complete reboot of my machine, without touching the bootloader.



edit1: Kexec is a mechanism of the Linux kernel that allows booting of a new kernel from the currently running one. Essentially, kexec skips the bootloader stage and hardware initialization phase performed by the system firmware (BIOS or UEFI), and directly loads the new kernel into main memory and starts executing it immediately.

    Please edit your question to clarify: What do you mean by "we can switch kernels without a reboot?" Can you provide an example? Do Virtual Machines satisfy your requirement?
