No way to create an EBS optimized instance

[rmg]

Every time I try to create a launch instance with a provisioned IOPS root, packer sits waiting while the EC2 console tells me the instance was terminated due to an invalid configuration.

AFAICT, using provisioned IOPS requires --ebs-optimized be set on the instance itself.

Am I missing something?

Is there a public AMI I could use to reproduce this?

[rmg]

I've been trying to do it with both Amazon (http://aws.amazon.com/amazon-linux-ami/) and Ubuntu (http://cloud-images.ubuntu.com/locator/ec2/) with the same results.

I was hoping I could do something like use provisioned IOPs for the launch_block_device_mappings to speed up the package installation phase of my packer builds.

You actually can do this using launch_block_device_mappings by making sure to set "volume_type" equal to "io1" and setting the iops. I think you'll have to select the proper snapshot ID too. This isn't any different than the console launching the thing, although the console prepopulates some fields for you.

I believe this may have been closed by mistake: https://github.com/mitchellh/goamz/blob/master/ec2/ec2.go#L259

I didn't have time to dig into it earlier, but mitchellh/goamz#94 does indeed look like it adds to the goamz library what I was looking for.
