The problem is that i'm fully based on LibVMI, which doesn't provide an API for 
page injection yet.

I think Tamas was waiting for a full support of pagefault injection on Xen 
before opening an API.

Maybe we should open an issue to track the progress about it.

Thanks anyway for the suggestion !
