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

["Nakajima, Jun" <jun.nakajima@xxxxxxxxx>]

The patch removes the 1:1 mapping against HVM guests from qemu-dm,
allowing to have bigger guests than qemu-dm. This is also the first step
for enabling balloning with HVM guests.

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.
