Additionally, I'm trying to figure out that solution. As I mentioned
previously, I think we can reserve all RMRR once when a guest call
XENMEM_machine_memory_map to create its own memory. What about this
idea? Or other better suggestions?

I don't think any HVM guest would ever call this, even more so that
the call is restricted to Dom0. The reservation needs to be done

Thanks for your correction. Actually I'm also afraid I may not find a correct place where I want to go indeed since I'm not familiar this process.

when guest memory gets populated (and its E820 constructed).

Could you hint me where this action is covered?

Thanks
