Yes, the binaries were correctly installed in /boot, but grub2-mkconfig wasn't creating an entry in grub.cfg for the particular combination of linux kernel and xen that I was looking for. Manually editing the grub.cfg appeared to work okay, but it was a pain because it gets over-written everytime grub2-mkconfig gets run.

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 at centos.org https://lists.centos.org/mailman/listinfo/centos-virt
