Hi,
Is it possible to host a split driver between 2 user
domains. There is no concrete documentation on doing so.
I have basically copied the NETIF backend and frontend drivers and
created the split TEMPIF drivers. I have also changed the python scripts
to create devices.
When used between dom0 and domU this works.
By changing the protocol type of device i was be able to send and
recieve socket buffers, by just adding network protocol hooks, like
ip_rcv().
But i am unable to do so between 2 domUs. Is there anything special
that i have to do.
I am using XEN 3.0 testing.
I have enabled the backend on one domU by adding the following line in
the boot config file as
>> tempif = yes
and added the following info in boot config file of domU hosting the
frontend
>> tempvif = [ ''backend=1'']
assuming domU hosting the backend is 1.
While creating the device using python script, without the following line
back = { ''hotplug-status'' : ''connected'' }
error when i execute xm create is
>>Error: Device 0 (tempvif) could not be connected. Hotplug scripts not
working
otherwise the device is created on the domainU hosting frontend, without
the probe functions calling the backend.
therefore i see NO ANY COMMUNICATION BETWEEN XENBUS and BACKEND for
TEMPIF drivers
thanks in advance,
looking forward for some insight
abhay
