[Xen-devel] live migration problem

[Xuehai Zhang <hai@xxxxxxxxxxxxxxx>]

i tried to live migrate a domain from a source machine to a destination
but i met the following problem:
   Error: Error: [Failure instance: Traceback: <type 'int'>, 1

i can see the migrated domain when i ran the command "xm list" on the
destination, however, when i tried to log in its console, it hanged there.

i attach the information from /var/log/xend-debug.log on the source
machine for your reference.

thank you in advance for your help.
