AWS has machine types that require ENA Support. You can run AWS CLI to find out if instance is ENA enabled.
aws ec2 describe-instances \ --instance-id i-xxxxxxxxxxxxxxxxx \ --profile default \ --region us-east-1 \ --query 'Reservations[].Instances[].EnaSupport' |
Login to the instance and verify.
sudo lspci | grep -i Amazon |
List driver details.
modinfo nvme |
Verify modules loaded at startup.
lsmod | grep nvme lsmod | grep ena |
If ENA drivers are missing, install them.
yum install pciutils |
