[Xen-users] Why domU not start automatically after server reboot
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.

[Xen-users] Re: Why domU not start automatically after server reboot
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.

Re: [Xen-users] Why domU not start automatically after server reboot
Le dimanche 24 janvier 2010 à 16:59 +0800, John Wang a écrit :> 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) : >Hello, A domain created with "xm create" is created, runs but is not "catalogued" so the machine can''t even start ! If you want "persistent" domains you have to create them with the "xm new " command. So the machine are registered and should start with "xm start". When the machines are OK, you copy their description files to "/etc/xen/auto" if you want then start at boot. But I don''t like that solution (with /etc/xen/auto) as the start is often a little bit to early eg : NFS or Iscsi mounts are not OK ... I prefer to do a start mith my own script when all the machine is started (start NFS and Iscsi at init level 3) and I start the machines at init level 5.
