[Libvir] [PATCH][RFC] shows scheduler information

[Atsushi SAKAI]

Hi, Daniel

Thank you for various comments.

Anyway I have several questions.
0)Is there any documents about libvirt/python/generator.py?
  It seems make python bindings from XML API description.
  
1)PROXY-API seems to be not fully supported to various read
  (for example vcpuinfo).
  This is just work is going or it is just a policy
  Anyway, this issue seems to be another work.
  I hope someone will do it consistently.
  If nobody do this, I will do it.

And one more,
Who attend the XenSummit?
I plan to go to the XenSummit.

Thanks
Atsushi SAKAI
