Hello, Markus I want to test PV patch but current patch does not work. (as Steven Smith suggested, for example xenfb.h xenkbd.h location is not correct) Could you give me a working version patch? Thanks Atsushi SAKAI >Summary of changes: > >* Use xenbus_device API. > > Some xm configuration magic is still missing, see below. > >* Negotiate features through Xen Store. > >* Key identification > > Discussed at length on this list.
