[Xen-devel] simple communication channel between domains

[Nuutti Kotivuori <naked@xxxxxx>]

This is really a xen newbie question, to which the answer might be
obvious if I only knew more of xen.

I wonder if there would be a simple way to set up a communication
channel between two domains - or specifically getting domain0 separate
communication channels to all the other domains separately.

Something akin to a UNIX-domain socket would be marvelous. Network
interface is a bit too much since it would have to go through the
network stack and several things affect it. Block devices are not
really nice for stream communication. And serial devices - I suppose
you can set them up between domains - have a baud rate, don't they?

So, is there something that would allow a single point-to-point
datastream between domains? If not, would making such a thing be a big
endeavour?
