On systems with grub2, grub-bootxen.sh is tweaking the global grub2 config -- making sure Xen runs first, and adding some default configuration. Even without that, grub2-mkconfig should be creating entries if the binaries exist. Are you sure: 1. That your new kernel & hypervisor have installed binaries in /boot? 2. That grub2-mkconfig is writing the config to the proper directory? (i.e., that, you're using the correct '-o' argument?) -George _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos-virt
