[Xen-devel] Xen - Guest memory allocation


        But if I want to add memory of type E820_USABLE to xen memory map during boot up (as per xen/e820.c) where the memory to be added lies behind a PCI device?

For ex,
If a PCI device reports it has 1GB of memory behind it.
And XEN has identified th RAM memory to be 4GB.

How can the PCI - 1GB can be added as usable memory to XEN's memory pool to get a cumulative size of 5GB;

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.)
