[Xen-API] Q on shared memory and evt-channel

[ravi kerur <rkerur@xxxxxxxxx>]

Hi,

I am trying to set up a shared memory/event-channels between 
dom0 and domU's via socket calls. I do not want to use existing 
front-end/back-end driver mechanism as it relies on devices aka vif, 
vbd type of device to be created and uses xenbus/xenstored for 
communication between domains. Adding support for new device similar to 
vif/vbd may require xapi toolstack changes as well which I would like to avoid. Instead 

1. write own socket library calls aka bind/connect and use them to 
setup shared memory and event channels between domains. I will have client and server side of application, server side running on dom0 and client side on domU's. 

or

2. write a kernel module(aka driver) and create devices under /dev/<some_device_name> in both dom0 and domU's and use these device to setup shared mem/evt_chnl. 

 I haven't 
sketched out details yet, but thought of checking if this would be 
feasible.

Thanks
-Ravi
