Hello.
I am an one of the developers of xway.
Firstly, I'm sorry for late response.
We(xway developers) have seen a reported your xway bug. But we didn't have
enough time to reaction.
Because of the our project's schedule, Now we don't have any time to solving
this bugs.
Currently we are working to enable migration of the guestOS using xway channel.
When our job is completed, we will try to resolve it ASAP.
We hope you to wait then,
and please notice the state of your work to me.
Best Regards
Chei-yol Kim

Thanks for the reply and pointing me forward.
Well xm dmesg is giving me nothing related to xway, that is why i never
included it in the message. But for more information, please find attached
strace output when I try to ssh from one guest to another. The xway switch
seems to work perfectly and routes us to shared memory (grant table) mechanism.
That is where the problem starts and communication stops. I think that is due
to xway driver.
one side note: I am not jumping to conclusions, but i guess the developers of
this
project have abandoned the project. :(. I have contacted them on the
email addresses provided, but so far no response. Or it can be that they are
terribly busy bringing it upto unstable tree. :)

At the moment, I feel
that xd.c (the xway driver) is causing the problems and the function
is
import_mem(...) and specific call is
BUG_ON(HYPERVISOR_grant_table_op(GNTTABOP_map_grant_ref, ops,
npage)); ...
This sounds like the driver is trying (and failing) to map a list of
grant references. Usually when this happens, you will see some output
on the Xen console (which you can read by typing "xm dmesg" in Dom0,
or attaching a serial line). This may help the developers - or people
on this list - to diagnose the problem.
Hope this helps.

Derek Murray.
