Re: [Xen-devel] [PATCH][HVM] Removing 1:1 mapping from qemu-dm

The patch removes the 1:1 mapping against HVM guests from qemu-dm,

It sets up mapping dynamically, and thus it can cause some latency for
I/O operations for HVM guests. I don't see visible latency yet, but I
think we need to tune the hashing size.
What do all the shadow-mode changes do? I see you add an extra
writable-mapping refcount to tlbflush_timestamp (only 4 bits) -- why is
that needed?
