Page 16 of the Condential Computing Deployment Guide - (AMD SEV-SNP & KVM) has the following instruction in bright red text:
“DO NOT SELECT HWE SELECT “Try or Install Ubuntu Server” and continue to the next step!”
However, the figures that follow on pages 16-17 depict interactions with the GRUB boot menu after selecting the “HWE Kernel” GRUB menu option.
One should ignore the HWE-specifics depicted in those figures, yes?
During the install, selecting HWE kernels will install a later kernel than the default 5.15.
GRUB has a quirk where installing “older” kernels (the 5.19-snp fork) will fall secondary to the newer kernels (the 6.x that HWE will install).
While one could go into the /etc/default/grub and modify your boot order manually, it is generally extra and unnecessary steps if one just uses the LTS kernel instead.
I will certainly get our document updated to make it clearer!
