Trying to figure the hyp out, I notice phys addr is set as:

which is set to 0x1019, totally baffling me. I'd expect it to be 32,
36, or 64????????
Of course it should be PAGE_SHIFT in here! c/s 14097 screwed this up
- sorry, my fault.
Yup, that fixed it. Can you pl explain in couple sentences how we are getting
at the physaddr_bitsize here?
I still don't understand why 37 is an OK size for a 32-PAE guest (i thought 36
was max).
Thanks,
