[Xen-users] dom0/domU communication

[Arijit Ganguly <aganguly@xxxxxxxxx>]

All, 
Is there a way to setup serial communication between dom0 and domU. The
idea is to have some way of exchanging messages between dom0 and domUs.

Certainly, it is possible to use s host-only network, and ssh or shared
file system to exchange data. However, there could be cases where the
dom0 is not networked. You may want to automate configuring domUs from
dom0. 

Any suggestions.

I vaguely recall iptables in very modern Linux kernels having
(experimental?) support for rules that take into account the user
attempting the connection.
