The latest CentOS 6.9 kernel update (2.6.32-696.18.7.el6 64-bit, which addresses meltdown) is broken on at least some Xen PV platforms and fails to boot. See https://bugs.centos.org/view.php?id=14336. You can't even get into grub from a remote console to select a working kernel. Well, you could set "default x", in /etc/grub.conf, where x = working kernel, before you update. Hindsight being 20/20. jbdigriz
