Would also like to mention I am not using Qemu and building some basic IO models around KVM (only using libkvm.h)

Subject: VGA address mapping?
Hi
I am implementing a VGA Device model. The model provides functions to read/write VGA memory space.
Just for testing I want to capture memory reads/writes to addresses 0xA0000->0xC0000 and forward it to my VGA model.
I have used following function to create physical ram
int kvm_create ( kvm_context_t<file:///C:/Documents%20and%20Settings/asaksena/Desktop/march_onwards/kvmsocket/doc/htmlkvm/structkvm__context.html> kvm,
unsigned long phys_mem_bytes,
void ** phys_mem
)
The function comments says that this creates a new virtual machine, maps physical RAM to it, and creates a virtual CPU for it. Memory gets mapped for addresses 0->0xA0000, 0xC0000->phys_mem_bytes.
I was expecting mimio read/write callbacks to capture transactions between 0xA0000->0xC0000 but I don't see that happening.
My question is how I can configure KVM to forward me reads/writes for VGA address space?
Thanks
Abhishek
