Rocky9 AMI does not boot on nano instance

Rocky Linux Help & Support

We are looking to replace some small jumpboxes in AWS accounts with Rocky9, and found that we are unable to boot the official AMI with nano instance type (such as t3.nano or t3a.nano), which is 1cpu x 512 MB memory.

We were able to confirm that we are able to boot into nano instance type if we use Rocky9 minimal ISO, but we would prefer to use the official AMI and not having to add another automation to our AMI build process.

I am not very familiar with the differences between Rocky9 AMI and the minimal ISO, and was wondering if someone might have some ideas.

Booting ISO is one thing, installation is another as well as running such installation with very little ram. Rocky Linux like RHEL has min hardware specs of 2GB of ram, but it can be ran with 1GB of which I have done personally, when things like sssd are disabled/removed plus any other unnecessary stuff. Anything less than this will be mostly problematic.

RHEL obviously set the minimum hardware specs for a reason.
