[Xen-users] domU crashs when creating multiple domUs to quickly
Hi Community, Is there a known problem with Xen when starting to many domUs to quick? I have a 64-bit machine installed with Xen 3.0.3, kernel 2.6.18 in dom0 and 2.6.9 in domU. I have absolutely problems with stability. But when I try to start the five configured domUs very quickly one after onther from the command line, some of them crash and I don''t know way. Can someone please help me to analyse this problem or at least point me to a FAQ where I can get more help? For those who are interressted in xend log, please find it attached. There is nothing noteable in /var/log/messages. Thanks, Jan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I''ve restarted xend to make sure that nobody has changed this and has not restarted the daemon. Why do you think that specifying this would help to solve the problem?

Try to specify:> > (dom0-cpus 1)> > Why do you think that specifying this would help to solve the problem?I have similar problem, which was related to SMP in dom0. The bug appeared only when I started many domains at once.
