Hi, I've installed FC4-T3 and then install the xen packages, following this manual: http://www.fedoraproject.org/wiki/FedoraXenQuickstart i've got to the step that i need to create change the domain0 RAM used, by runing: xm balloon 0 384 it didnt work becuase the xend is not runing, i've tried to start it by issuing: /etc/init.d/xend start after a few seconds it finished and i checked to see if the xend is up, ps -ef | grep xen returned only [xenblkd], the logs xend & xend-debug return no new lines, can some one please tell me what's wrong or how i can debug this? (I'm using the latest Xen packages) thanks, Oded.
