You're a lot better off go over to the Linux Kernel Devel site. AFIK kexec can only do this on real hardware. I think your better off scheduling downtime for the server. Although kexec does have a site page. John _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
