Hi,
1. How should we allocate extra memory to guest other than memory allocated through
"qemu_alloc_physram"??
qemu_alloc_physram() is obsolete. I've just removed it to avoid
confusion (and a warning).
I presume you want to give kvm memory which is not real RAM - from a
host device?
hw/device-assignment.c does that.
Please clarify what you want to do.
2. How to register the extra allocated memory with KVM?
cpu_register_physical_memory(), but that has to come from qemu_ram_alloc().
As a hack, you can call qemu_ram_alloc(), and then
mmap(qemu_ram_ptr(ram_offset), ... ) to replace the RAM with device memory.

Do not meddle in the internals of kernels, for they are subtle and quick to
