I am just a new man in kernel development, there is a question bother me for a time. Is it neccessary to have a virtual machine when developing or debugging kernel?
Thanks.

No, it's not. But it could be convenient if you don't want to hurt your
machine.

If you are working on something unrelated to real-hardware then using
a virtual machine can help you, like not having frequent reboots
of your physical machine maybe you've only one development machine
then you can try and attach gdb to the virtual machine
from your host machine.

If however you've a real hardware then using a real machine would be better.

Being able to access the machine monitor is very useful at times.  It
lets you look at registers, memory, hardware, etc.  I also appreciate
being able to quickly boot a kernel with the -kernel option.
