Its possible that the ami you are trying to launch requires an EBS. With an EBS you can set the IOPS value which seems like it is not set and is giving you the issue.

Having a look at the documentation it seems you might need to add

--ebs-size 10
SIZE as an option.

I got that from the knife documentation http://docs.opscode.com/plugin_knife_ec2.html

Also taking a look at the source code for the knife ec2 plugin it looks like you can add.

--ebs-optimized 
Enabled optimized EBS I/O
