[Qemu-discuss] Print Memory Address Range

I am new to qemu development. I wanted to print the corresponding addresses involved when a memory has been assigned to a virtual machine.

For example, when i invoke the following command

qemu-system-i386 ubuntu.img -m 1G

I need to be able to print the virtual addresses and physical addresses involved. Like above 1G memory involved:

Guest Virtual Addr = 0x12345678..to 0x87654321..

Guest Physical Addr = 0x23456781..to 0x74536733..(This is the one that gets mapped to host virtual memory if my understanding is right).

Note: Above numbers are just for explanation.

When I looked into the source code of qemu, I see that this size whatever we are mentioning in the command here is assigned as a part of |ram_addr_t| block. But I am not able to find as how to proceed to find the corresponding addresses for this size. Once I find the addresses, I need to perform the encryption of the contents present at this location.

Kindly help me in this regard at the earliest.
