Xen devel - Feb 2005 - Migration Errors

Hi, 
I am trying to migrate a domain (testDomain) from node1 to node2. 

Here is some information about the problem: 

node1#: xm migrate testDomain node2 

After the command is executed, there is some communication between the node1 and
node2 Xen hosts.

xfrd daemon (which is forked by xend) is primarily responsible for vm migration
and there is error in its log (/var/log/xfrd.log)

The exact error is (on node2): 
Unrecognised state format -- no signature found (The logs at node1 show that the
state of the domain was sent but error was received)

On node1: 
/var/log/xend-debug.log: 
clientConnectionLost> connector= <twisted.internet.tcp.Connector instance
at 0x40a1160c> reason= [Failure instance: Traceback:
twisted.internet.error.ConnectionDone, Connection was closed cleanly.
(It seems "Twisted" is giving errors in the internet connection.
Twisted is a pre-requisite required by Xen, and is used to write network
applications.)

Has anyone encountered this problem before? 

Thanks, 

Amitabh

Hi,

This is most likely the same problem as I have, you will find that xm  
save doesn''t work either.

match=arthur+bergman

is the thread that I describe this, I am stuck now because I don''t know
how to get the required debugging information.

the segfault is inside libxc called from xfrd
