Edit grub's entry and add "noreboot" to your xen parameters, maybe when the
kernel panicks xen detects it and automatically reboots it.



"noreboot" grub.conf option still produced nothing other than a flashing cursor on the top left. Also, neither num-lock nor caps-lock respond at this time... I seem no closer with helpful information other than, "it's broken" :(
Here is the grub.conf stanza for the kernel:
title CentOS (4.9.16-24.el6.centos.plus.x86_64)
root (hd0,1)
kernel /boot/xen.gz dom0_mem=3G,max:3G cpuinfo com1=115200,8n1 console=com1,tty loglvl=all gue
st_loglvl=all noreboot
module /boot/vmlinuz-4.9.16-24.el6.centos.plus.x86_64 ro root=UUID=bc0727e1-882c-4fbc-a4d9-e4c
f754d72b7 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  K
