Hi Team,

I was went through Live Migration source code in Qemu. I didn't find any specific API for NUMA which can able to copy the dirty pages for Local and Remote memory corresponding to individual CPU core.

As I understood, in NUMA aware Intel CPU Processor has one Local memory which is attached to dedicated CPU core (individual) and also can able to access remote memory. So during Live migration, dirty pages can be created in local memory and as well as can create in remote memory also. 

My query is, is there any source code or API exposed in Qemu which can able to access that offset addresses of Local memory and Remote memory and then able to copy the
dirty pages? If "yes" can you please let me know how it will work? If "No" then I need to think different approaches.

Please let me know if my query is not clear to you. I hope this is the right place to put this query.

Thanks & Regards
Arkajit Ghosh
