I've scoured Google and the AWS developer forums pretty thoroughly (I think) and can't seem to find an answer.
I'm snapshotting EBS volumes with boto3 daily for DR purposes. Some of the instances using these volumes are t3., some are t2..
I'm able to create an AMI from the snapshots, great! However, when I try to create an image of the same type (namely t3.*), the console is grayed out and says, 'This instance type requires ENA support etc...'.
What's strange is that the instance does support ENA
$ sudo modinfo ixgbevf version: 4.1.0-k-rh7.5
When I create an AMI from a t3.* instance via the CLI, the AMI supports ENA and all is well.
The problem, though, is that I'd like to be able to build AMIs from snapshots. Hopefully someone can shed some light on this!
