Hi there, my problem got solved. It's due to that there is no free space in my dom0 disk. The xen do show this hint,but i ignore them and rush around to find out if there is config mistake. so stupid. Anyway, after i found the reason, i make room for dom0 disk by delete some big files. but it still failed to start xend daemon. finally I find the some posts like this one http://forums.novell.com/novell-product-support-forums/suse-linux-enterprise-server-sles/sles-virtualization/343286-unable-connect-xend.html and this one: http://lists.xensource.com/archives/html/xen-users/2007-10/msg00799.html According to those post i just delete all the stuff in the directory /var/lib/xend and /var/lib/xenstored and /var/run/xen*.pid and kill the xenstored process. And at last reboot the server. Now everything is ok. great! Sorry to bother you.

A problem is when I reboot the serve(with domU status is "-b----"), the domU will not get started automatically after the server booted. But i can start those domUs by using the command "xm create myDomU1.cfg" in the shell prompt with on error. The domu can restart automatically orginially. But when i change some configuration, it now failed to restart. unfortunatelly i dont know which settings cause the problem. I check the xend.log and found some error message(see below). Anyone can help ? The following information may help you to figure out the problem: My configured domUs(I start them manually) : ######## Begin running domUs ######## svr1:/etc/xen# xm list Name ID Mem VCPUs State Time(s) Domain-0 0 349 1 r----- 18.0 j1xen 3 768 3 -b---- 5.9 j2xen 4 512 3 -b---- 5.1 j3xen 5 384 3 -b---- 6.2 ######## End running domUs ######## ########Begin /var/log/xen/xend.log ######## [2010-01-24 14:54:24 2517] INFO (SrvDaemon:331) Xend Daemon started [2010-01-24 14:54:24 2517] INFO (SrvDaemon:335) Xend changeset: unavailable.
