Adding memory to host for XCP-NG host

I added additional memory sticks to the host and when it booted into XCP-NG, it went through all the scrolling and then it stopped here for about 30 seconds…

Not sure what this means

Not an XCP-NG expert but this seems similar to (older thread): XCP-NG 8.1 | [ 4.848474] efi: EFI_MEMMAP is not enabled · Issue #377 · xcp-ng/xcp · GitHub

Ironically, there is one on a Microsoft site that indicates that you may have to add some kernel paramaters:

You then need to locate the kernel parameter within this file and add the following to the end of the line:

add_efi_memmap

I’d like to know what’s going on, since I built my hosts in a way to add more ram later, and also upgrade the CPU later to bring more of each. This is an aspect I never thought to test, I just assumed, add more ram modules and swap to the same family of CPU with more cores and I’d be ready once the BIOS adjusts to the new values.
