[Xen-users] communication between dom0 and domu

[Arijit Ganguly <aganguly@xxxxxxxxx>]

All, 
Is there any way we can set up a communication channel (not a TCP/IP
based network) between domain0 and unprivileged domains. This can be
useful in a way that we can write automatic configuration mechanisms
for our unprivileged VMs.

Illustration:
I have a domainU running on a host, which doesn;t have network
connectivity (like ssh). I just use the VM as a environment I can
issue commands and get results.  Ports on domain0 are blocked
preventing me from accessing the VM console. I do not have an account
in domain0 for security.
What can be done is running a truested software on domain0, which
takes commands and runs them inside domainU and returns me the
results.

The bottomline is a communication channel between dom0 and domU. Any ideas?

Arijit
