Migration is quite big - so take a step back first and understand how
a migration works before diving into the code too far.
First I'd suggest going for something newer than 6.5 - it has a very
very old QEMU on it;  If you can upgrade to a 7.x it'll make your life a
lot easier for building and working with current code.

The current QEMU has a whole migration/ subdirectory with quite a bit of
code, and there's also some kernel code that helps, and code in
individual devices.

Then there's also the code in libvirt that drives it.

A lot of code - so the trick is to figure out what you want to change
and then find the right place.
