Hello there, I have new installed a debian lenny server(intel Xeon E5504, 4 cores) with xen(3.2-1) vms . 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.
