Thanks a lot Martin.
I have some more questions. How in VMM I can read contents of VM's RAM by accessing the physical memory address directly instead of virtual address? Or is MMU in Genode configured for one to one mapping the virtual address to physical address? how do i use DMA without involving the CPU to read contents of VM's RAM inside VMM?

Thanks,

I've recently wrote an answer to another question on the mailing list
that should also answer your questions:
