Hi all,
I''m having problem testing migration (live and regular).
I''ve
activated a relocation server on both my machines (fisrt one is a
fedora5, second one is a debian), chosen 8002 as relocation port and
allowed connection from the Internet.
(xend-http-server yes)
#(xend-
unix-server yes)
(xend-relocation-server yes)
(xend-port 8000)
(xend-
relocation-port 8002)
(xend-address '''')
#(xend-address localhost)
(xend-
relocation-address '''')
(xend-relocation-hosts-allow '''')
#(xend-
relocation-hosts-allow ''^localhost$
^localhost\\.localdomain$'')
etc.....
I rebooted my machines when edited xend-config.sxp.
My
Machines are on the same L2 subnet and there are not route problem
between them.
that''s what prompts me when I try migrating:
[root@localhost fedora6]# xm migrate 13 143.225.229.137
Error:
/usr/lib/xen/bin/xc_save 18 13 0 0 0 failed
Usage: xm migrate <Domain>
<Host>
It seems a problem when saving VM state. However if I try with
xm save I''ve no problem with it...I can also restore VM execution from
the file generated with xm save.
Here is the xend.log:

however, I
haven''t yet used a networked solution for my disk images.
they''re
stored on local hard disk.I wanted to be sure of my configuration
before, facing the problem after.
So I don''t expect migration
successfully terminates, but at least begins...
But I don''t think It''s
the reason for which migration fails...
Let me read good news!!!
