Please help me...as the error message mentioned: It seems that your xend is not running. I do not know opensuse from mind so far, but usually there should any init script in i.e. /etc/init.d/ like "xen" or "xend" you have to start or make shure that it would started during boot (may be in YaST - init). I.e. try to find and start: /etc/init/d/xend start and then check with i.e. ps afux and or netstat -alnp if "xend" is there and/or offers any connections. good luck and best regards, Niels. - -- Niels Dettenbach Syndicat IT&Internet http://www.syndicat.com -----BEGIN PGP SIGNATURE----- Version: APG v1.0.8 iIEEAREIAEEFAlAn2Wk6HE5pZWxzIERldHRlbmJhY2ggKFN5bmRpY2F0IElUJklu dGVybmV0KSA8bmRAc3luZGljYXQuY29tPgAKCRBU3ERlZRyiDezRAJ919W7GjN9M NM50y3OHOjw0YD3BUQCfY+CXDOHCY0764WAAty2gwXpCqbs=16Lt -----END PGP SIGNATURE-----

Then try to start xencommons / xend again (xencommons should started automatically when starting xend as a dependency on most linux distros). Usually it is a better idea to compile that xen stuff statically into the kernel - not shure if/how SuSe does this within their own distro kernels. hth best regards, Niels. -- --- Niels Dettenbach Syndicat IT & Internet http://www.syndicat.com PGP: https://syndicat.com/pub_key.asc --- _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Can u explain me ? thx for you patienceXend is a process which serves the xen functionality i.e. to the user etc. It should offer at least a socket like: /var/lib/xend/xend-socket see i.e.: netstat -alnp |grep xen and/or lsof /var/lib/xend/xend-socket It allows more connectivity i.e. for inter-machine work but this is out of scope here att i think. Xend should running as a "process": ps afux |grep xen btw: pls stay on list if you need answers / help here. best regards, Niels. -- --- Niels Dettenbach Syndicat IT & Internet http://www.syndicat.com PGP: https://syndicat.com/pub_key.asc --- _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
