This may be of use. When it fails, the dom0 reports:

        Xen reported: 6799.922 MHz processor.
        ...
        Calibrating delay using timer specific routine.. 17069.04 BogoMIPS      
(lpj=34138093)

When it works, dom0 reports the correct numbers:
        Xen reported: 3399.952 MHz processor.
        ...
        Calibrating delay using timer specific routine.. 8505.35 BogoMIPS 
(lpj=17010701)

Strange that the numbers are basically 2x the correct values.

Also have had it fail at a lower memory (96GB) with all
64 CPUs. When I was running a HV built for only 32 it worked
until I passed 112GB to dom0.
