However, it *does* properly boot under the "CentOS Linux (4.9.20-25.el7.x86_64) 7 (Core)" grub2 menu option! A semi-close look at the /etc/grub2.cfg yields no discernible difference between a properly functional Dell R620 and the non-properly functioning Dell R710. Sorry, I had been distracted with other issues and have not yet submitted information to the xen-devel group yet. Thanks PJ
