As I wrote a few weeks ago. Both issues ("mem banks exhausted" and 
"Cannot exit boot services") are meant to be non-fatal. So you should be 
able to continue booting Xen afterwards.
The fact you don't see any log seems to suggest that you didn't enable 
properly earlyprintk. Would you be able to post your xen/.config?
Could you also confirm which server are you using? The ACPI table seems 
to suggest this is an Ampere Altra.
Best regards,
