I'm trying to figure out how to replace the vmlinuz and initrd.img from CentOS 7.4 with "fixed" kernel-plus versions in order create CentOS 7.4 VM's. So far I'm stuck booting via 7.3 install, adding new kernel-plus and upgrading to 7.4. I've not found any complete Google answers and was looking

Apologies: I installed the newer -26 kernel and had not rebooted into it. The grub2 menu item should have been "CentOS Linux (4.9.20-25.el7.x86_64) 7 (Core)". I am currently restarting that remote affected system (unmodified grub2 entry first). Thanks PJ On Tue, Apr 18, 2017 at 8:39 AM

Updating my CentOS 6.8 Xen server with new 4.9.13 kernel yields a kernel boot message of a few like "APIC ID MISMATCH" and the system reboots immediately without any other bits of info. This is on a Dell R710 with 64GB RAM and 2x 6-core Intel CPU's. As an additional test, I installed and attempted
