How to install and enter the compiled kernel

[linxiaobo]

Hi,

My aim is to change some code in Linux kernel to adjust some new
function.

I have downloaded the souce code from www.kernel.org and make the
kernel as follows:
"make O=output menuconfig"
"make bzImage"
"make O=output module"
and the compile is successful, vmlinux is there

My question is how to enter my own linux system so I am able to check
if my changes work. Does linux kernel generate iso img so that I can
install it in my virtual machine?

edit your bootloader to add a menu option for your new kernel.
you need to have the bzimage in /boot for it to work.
