Untuk mengaktikan dukungan ENA ada beberapa cara seperti berikut

Edit Instance attribute (enaSupport)

  1. Stop instance
  2. Ubah instance type yang mendukung ENA. Misal t3.micro 
    1
2
3

    aws ec2 modify-instance-attribute \
--instance-id instance_id \
--instance-type t3.micro
  3. Edit attribute 
    1

    aws ec2 modify-instance-attribute --instance-id instance_id --ena-support
  4. Cek attribut EnaSupport 
    1

    aws ec2 describe-instances --instance-ids instance_id --query "Reservations[].Instances[].EnaSupport"
  5. Jika respon true, maka Instance dapat Anda start

Register Image mengunakan snapshot

1
2

aws ec2 register-image --name image_name --root-device-name /dev/xvda --block-device-mappings DeviceName=/dev/xvda,Ebs={SnapshotId=snap-07727834796a6d224} DeviceName=
/dev/xvdb,Ebs={SnapshotId=snap-01d319f8a7223deac} --ena-support

Lalu luncurkan instance dengan tipe instance yang sudah mendukung ENA

1

aws ec2 run-instances --image-id ami-03b29257f3ffb6034 --instance-type t3.micro --key-name key_name

Test ENA

Test ENA apakah sudah aktif di instance
