paravirtualization

paravirtualization

[Omar Khan]

The paravirtualization announcement by Ingo Molnar said that:

- it provides an ad-hoc paravirtualization hypercall API between a Linux 
  guest and a Linux host. (this will be replaced with a proper
  hypercall later on.)

Is it possible to modify a non-linux guest to take advantage of this hypercall
API? or are there conditions that prevent us from doing this?

Source code would be required... this eliminates several of the
interesting cases.  But I suspect any flavor of BSD could be so
modified, provided you use only the external interface and no linux
code (because BSD won't accept GPL code).

Someone correct me if I'm wrong, but calling the hypercall API is
out-of-process, and thus can be done without adopting the GPL?

Paravirtualization

[xeb-JGs/UdohzUI]

On official web site said:
In progress:
    * Paravirtualized networking
    * Paravirtualized block device

Where can find sources of that work, if it is possible ?
