AFAIK, In para virtualization, when guest boots, it reads the memory layout from a special page (start info page) instead of from bios.
If your guest os is a PV Linux, you can check its source code (e.g. start_kernel(), etc.)

Looking into the xen code for days, I still could not figure where the following occurs,

How does xen allocates memory to the DomU guests?

Where in the code does xen provides the start and end address map for each guest that is created?

Ovreall, How does xen creates a memory pool and performs allocation?

Any help in this regard would be appreciated,
Thank you in advance,
