[RFC PATCH v6 00/28] libxl: Deprivilege qemu

[Ian Jackson <ian.jackson@eu.citrix.com>]

This is a new version of Stefano Stabellini's series
  [PATCH v5 0/6] libxl: xs_restrict QEMU

I took Stefano's code as a spec for how to interact with qemu, and
have reworked the whole series.  In particular, I have
 - rebased onto staging
 - split up some of the larger patches
 - restructured the patches so that every intervening version should work
 - redone the async task handling
 - provided what seem to me to be appropriate configuration options
 - shaved a few yaks (although I tried to limit this!)
 - fixed the cross-version compatibility
 - reduced the new permission grant for the domain to only .../physmap

I have compiled this but I haven't tested it yet.

I think it would be very useful at this stage for others to read the
commit messages, internal docs, and important structural elements.

Detailed code review should probably wait until after testing which in
turn ought to wait unil we decide what (if any) design and interface
changes are needed.

And I don't expect to get any feedback until the new year :-).

Happy holidays all.

Regards,
Ian.
