The --boot-mode is lacking "uefi-preferred" option

[ypismerov-tmx]

Describe the feature

There are cases uefi-preferred has to be set up for AMI to be able to work with AWS metal instances (dedicated hosts).
It is currently missing. Only uefi and legacy-bios modes are supported by --boot-mode.
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ami-boot.html lists of currently supported boot modes.

Use Case

1. To support all currently available boot mode options.
   2, To support creation of AMI images (via image-import) that can work with AWS metal systems (dedicated hosts).

Hi @ypismerov-tmx thanks for reaching out. What specific CLI commands are you trying to use --boot-mode? Here are all of the ec2 commands for reference: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ec2/index.html.

From the EC2 service API models (used by both the AWS CLI and Boto3) it looks like uefi-preferred was added 14 months ago to BootModeValues:

(Here is a link to the commit. And it looks like this is the related line in the CLI CHANGELOG.)

You mentioned using 2.15.38 which is a recent version, so I would expect the --boot-mode support for uefi-preferred to be up to date. If you want to share your debug logs (with sensitive info redacted) by adding --debug to the command, that could help give more insight into the issue. Depending on the information we receive, we may need to reach out to the EC2 team to verify that their API models are up to date in regard to this parameter.

import-image Just noticed the option not supported for that command. I guess my request is invalid. We can close it. The uefi-preferred boot mode isn't supported for importing images.

Thanks for following up - yes from the import-image command documentation it looks like uefi-preferred is not supported:

(That option is still listed under "Possible values" because it is modeled to be used across other APIs/commands. But the note was added there for clarification.)

Here is the boot modes page in the VM Import/Export User Guide for more information.
