  Hi folks,

Here are a bunch of patches which start adding xen support to qemu.
Overview (individual patches have longer descriptions):

  #1 -- groundwork: build system, cmd line options, ...
  #2 -- xen backend driver infrastructrure
  #3 -- xen console backend driver
  #4 -- xen framebuffer backend driver
  #5 -- xen block backend driver
  #6 -- xen nic backend driver
  #7 -- allow xen disks and nics being configured via qemu command
        line options.

With the first four patches in place upstream qemu can replace xen's
qemu-dm for paravirtual domains.  The block and nic backend drivers are
full userspace implementations using the grant table device (gntdev).

xen support is implemented using another machine type.  xen's qemu-dm
already uses the machine type to switch between paravirtualized and
fully virtualized machines, so this was the natural choice.  qemu has
gets a new "xenpv" machine type additionally to the "pc" and "isapc"
ones.

I've placed the new files into the hw/ directory.  With all my xen bits
(partly not submitted yet with these patches) those add up to 18 new
files, all prefixed with xen.  Hmm, maybe I should better place them
somewhere else, so the already quite crowded hw/ directory doesn't
become even more cluttered?  If so, any suggestions?  New toplevel
directory?  New subdirectory below hw/?  Something else?

Comments?

cheers,
  Gerd
