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

hi Thank you for your explanation and when xen processes " live migration",xend will fork a process to do xc_linux_save,and also call the helphandler which will call migrateDevices() in three steps,that is ,migrateDevices() will copy the devices'' state to the destination when the iterative pre-copying of the VM memory state is completed ,is it? or what is the tricks behind? i read DevController.py,but still not clear, and i am confused about which code is called in the destination node to cooperate with for migration, that is ,on the destination node ,which code will invoke the receiving function there? is it httpserver? then ,which function code will it call to receive ,or what to do ?i guess some functions will be called to deal with something ,then call the restore function or something, but which function is called before the restore function is called ? i am lost in it Thanks in advance Stefan Berger 写道:> > xen-devel-bounces@lists.xensource.com wrote on 01/02/2008 01:41:56 AM: > > > hi > > I read the code of migration,and i am confused about the function of > > migrateDevices(), it is called for 3times,and what is the function for > > it ? could someone help me out > > The purpose of this function is to enable the migration of ''external > devices'', i.e. this would be disk images or TPM state, from one > physical machine to another while migrating a vm. > > The prototype of the migrate function explains the different steps. > > http://xenbits.xensource.com/xen-unstable.hg?file/2491691e3e69/tools/python/xen/xend/server/DevController.py > > > > Stefan > > > > > Thanks in advance > > > > _______________________________________________ > > Xen-devel mailing list > > Xen-devel@lists.xensource.com > > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

hi I read the code of migration,and i have got some confusions, the source node sock connect the destination node with which port? 8000,is it ？and when migration is processing ,the relocation server is invoked ,is it ? and the relocation server is using port:8002? is it ?and the source node copy the memory state ,say dirty page, through port:8000 to the destination node, while the VM-migrating''s networking data is send to relocation server, is it? or how does it work? could someone help me Thanks in advance _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Sorry you''re having trouble with xway. I''ve not tried it myself and I''ve also not known of anyone else actually running it... It might be a good idea to try and contact the xway developers directly in case they don''t read this list, or you could cc them on these e-mails.. Perhaps there''s a contact e-mail address for the developers somewhere in the source code? I have a Powerpoint presentation on Xway that I downloaded when it was first announced; the presentation was by "Kangho Kim, System Software Team, ETRI". ETRI = Electronics and Telecommunications Research Institute. Maybe you can find some contact details for him through Google?

Hi Thanks for the reply. I did contact the developers but there was no reply perhaps my mail got lost in Christmas junks. I shall try to contact them again, in fact this email is bcc to the developers. I placed a help request at xway forum at source forge as well (though it contains only my initial observations, as xway only gets complied for x86-32). 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)); ... I shall keep trying, as I think good work shall not go to waste.

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.

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. :)

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.

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. :)

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.

hi i am interested in your work about "to enable migration of the guestOS using xway channel", what does it mean? does it mean that you try to enable the VM with xway channel to make live migration, or not?

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.

Though I am not the developer but I had a chance to look at the code of Xway. You are quite right, this is exactly what they want to achieve (ref their previous email communication at Xen-devel list-sometime may-june last year). Xway''s initial version had a restriction of adding IP addresses of guestOS at the compile time so that Xway switch can know that if the two guests share common physical host. If yes, they switch to Xway mechanism, else normal sockets are utilized. IMHO the biggest challenge is not to dynamically update the list of guestOS sharing same physical host, but is to handle the migration itself. The Xway sockets (grant tables) will break and the data can potentially get lost. Then new sockets will be created and the data which was already supposed to be on its way through Xway, now needs to be collected back routed through normal sockets. It was be interesting to see how developers touch these issues.

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.
