Xen devel - Feb 2006 - Problem migratin domain

Hello friends,
I''m having problems migrating domains with Xen3.0. I''ve used
migration
Xen2.0.7 with no problems and now that I''ve upgraded it to Xen3.0, I
get this when I do a migration (not even a live migration !!!, it''s a
standard migration).

XenRunner:/var/cache/apt/archives# xm migrate 29 192.168.50.212
Unexpected error: httplib.BadStatusLine

Please report to xen-devel@lists.xensource.com

I''ve been looking for a long time in mailing list and there are some
thread about migration problems, but not the same that I have.

Thank you very much.

Regards,
 Miguel.

Any ideas? I''ve got no clue. My python version is 2.3. Is it fine?

This is what i found in /var/log/xend.log:
