There was a note that the non-Xen kernel at the same kernel version did
indeed boot:
"CentOS-6 4.9.20-26 kernel exhibits the same constant
kernel-start-then-reboot issue when booting under the "CentOS Linux, with
Xen hypervisor" grub2 menu option. However, it *does* properly boot under
the "CentOS
Here is something interesting... I went through the BIOS options and found
that one R710 that *is* functioning only differed in that "Logical
Processor"/Hyperthreading was *enabled* while the one that is *not*
functioning had HT *disabled*. Enabled Logical Processor and the system
starts without
Just to note, the same pattern happens on C7:
"CentOS Linux, with Xen hypervisor" = reboot
"CentOS Linux (4.9.20-26.el7.x86_64) 7 (Core)" = boot

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
