I've tried going through the source code but didn't understand much, and couldn't find documentation either. I want to work on live migration and need help getting to know the code. More specifically I want to understand - where the pre/post copy algorithms are implemented - which files/data-structures that I should look at - should I need to make changes, where and how should I start? I am new to working with such large code bases, hence need some guidance.

Hi
I am trying to understand how migration,= more specifically live-migration works in QEMU. I've tried going throu= gh the source code but didn't understand much, and couldn't find do= cumentation either. I want to work on live migration and need help getting = to know the code.
More specifically I want to understand
- where the pre/post copy algorithms are implemented
- whi= ch files/data-structures that I should look at
- should I need to= make changes, where and how should I start?

I am = new to working with such large code bases, hence need some=C2=A0guidance.

Thanks
