[Xen-devel] [PATCH for-next RFC 0/8] Port Xen to Hyper-V

[Wei Liu <wl@xxxxxxx>]

Hi all

In case you're wondering, I can already run a fully fledged Xen system on
Hyper-V with emulated disk and network.

This is the very first stage for porting Xen to run on Hyper-V with all the
goodies Hyper-V has to offer.  With this series, Xen can successfully detect
Hyper-V and prints out a message.  I would like to first get the directory
structure and kconfig options agreed upon.

There are two major areas to be worked on:
  * Make Dom0 able to use Hyper-V's synthetic devices.
  * Make Xen use of the synthetic timer, reference TSC and enlightenment VMCS
    and other interfaces.

They aren't trivial, and time can be scarce on my side, so I intend to post
patches piece meal when they are ready.

Questions and comments are welcome.

Thanks,
Wei.
