[libvirt] MemoryPeek() is slow

Hi, I play around with MemoryPeek() API on QEMU. While it works well, I found that it is too slow. That is expected because of the way it works: we always need to save memory to a file, and read it in again, and that is too inefficient. I am trying to figure out a better way to do this. To do that, clearly we need to re-architecture QEMU for this: We must have another way to read memory from outside the QEMU process. Anybody could suggest a solution for this problem? I am willing to spend time on this feature to improve the situation. Thanks, J
