Hi,

Is there an escape mechanism that would allow a guest kernel in dom0 to directly access the memory space of the VMM without having to go through the hypercalls? I want to be able to mess with physical pages from within dom0 and perhaps with some vmm data structures from outside of the vmm.

I know this breaks strict layering and isolation properties but it would be useful for a tool i'm trying to build.

Thanks,
Mike
