[Xen-devel] xway issues / bugs

[Muhammad Atif <m_atif_s@xxxxxxxxx>]

Dear Developers,
I have tried using the interdomain communication patch for xen (Xway, http://sourceforge.net/projects/xway) a link of which is there at Xen wiki. I am having troubles getting it going. I am using AMD Opteron 248 (64-bit), with 2 GHz ram and IWILL motherboard. My distribution is ubuntu 7.04 and I am using Xen 3.0.3 for i686, as xway patch suggests that it is only for 32 bit systems. The GCC version is 4.1.2. I have also tried  xway on another machine which has 32 bit intel processor.
During the boot time, i see in the dmesg output giving me "net/ipv4/xway_proto.c:xsw_accept:143: inet_accept() err=-11" on Opteron. The intel 32 bit gives NO message of this type. Now to the heart of the issue
I can get the xway daemon and other related stuff loaded without any errors or warning. Upon simple ssh from one domU to another (i have compiled the ip addresses as instructed) i get a printf on screen on the receiving domain "client_sock = 5" and that is where both the domains stop processing i.e. ssh doe not seem to progress any further. strace is not helping me that much. I have noticed that xwayd.c (daemon) gives a write() call and this call is returning 0, instead of the message size.

Has anyone ever come across this error/bug? or simply has anyone ever tried xway?

 

Best Regards,
Atif
