I recently went through a frustrating experience trying to get Xen 4 running on a CentOS 7 system.  After a fresh install, fully updating the system, rebooting, then trying to install Xen4CentOS it would fail to boot into the 4.9 kernel, sitting there with a blinking cursor indefinitely.
Check the BIOS to see if Hyperthreading is disabled. If so, enable it. I had some Dell server (Dell R710s and R610s) that I finally figured out would not boot like you describe when HT is off for some reason.
