It may take a few minutes for the AMI to be created. After it is created, it will appear in the AMIs view in AWS Explorer. To display this view, double-click the Amazon EC2 | AMIs node in AWS Explorer. To see your AMIs, from the Viewing drop-down list, choose Owned By Me. You may need to choose Refresh to see your AMI. When the AMI first appears, it may be in a pending state, but after a few moments, it transitions to an available state.
