Re: [Qemu-devel] About address mapping between host and guest in QEMU

[Wenjie Liu]

The thing I am trying to achieve is to get the data and guest physical address of every guest memory access, so I need to known which API can be used to do the address transform.

Thanks a lot.

It might help if you explained at a higher level what you're
trying to achieve. Usually you don't need to manually try
to do this conversion from guest to host address because
there is an API which will do whatever memory operation
you wanted for you (including finding the host address,
dealing with the case where the guest physical address is
an MMIO device or has nothing mapped, and so on).
