Hello,>But why won''t migrating to another Host work?1) What is the error log you get in /var/log/xend.log If you get in the command line: "Error: can''t connect: Connection refused" there are chances that /etc/xen/xend-config.sxp is not configured right on the other side (to which you want to migrate). see my answer in http://lists.xensource.com/archives/html/xen-users/2005-11/msg00391.html 2) I added today some details on migration and migration configuration in my XenIntro wiki page: http://wiki.xensource.com/xenwiki/XenIntro Regards, Rami Rosen On 11/24/05, DIEDERIT@ing.boehringer-ingelheim.com < DIEDERIT@ing.boehringer-ingelheim.com> wrote:> > But why won''t migrating to another Host work? > Same subnet!!!?!?!? > > Thomas Diederich > > ************************************************** > * Boehringer Ingelheim Pharma GmbH & Co.KG > * A Informationsverarbeitung / Diplomant Systemtechnik > * > * Mail: diederit@ing.boehringer-Ingelheim.com > * Phone: +49 (0)6132/77-98151 > > > -----Ursprüngliche Nachricht----- > Von: xen-devel-bounces@lists.xensource.com > [mailto:xen-devel-bounces@lists.xensource.com] > Gesendet: Donnerstag, 24.

Migration will also not work!1) Please run tail -f /var/log/xend.log from a different terminal and then run the migrate command (as I understanf you are migrating to 148.191.190.3 Please post the messages from /var/log/xend.log after issuing the migration command. This may help to diagnose the problem. Also if there is any message on the terminal on which you issued the migrate command please post it. Also make sure that you have enough memory on the host to which you want to migrate (though I assume you did it after the problem you had before). 2) It seems that the target to which you want to migrate does listenin correctly on port 8002 to TCP connecttion as telnet shows (By the way, nothing indeed should happen after displaying >Escape character is ''^]''.)
