Yes, this is the new way of specifying instance type, it allows you to use
restricted attributes that the user couldn't use otherwise and share
different instance types among different user using the opennebula
permissions. You can still use the old file based templates changing the
use_file_templates var in econe.conf. But I recommend using the new system.

The template should not contain the DISK since it will be generated by the
econe-server using the information provided by the user, same for the user
data and keypairs. You can check the code here:
https://github.com/OpenNebula/one/blob/master/src/cloud/ec2/lib/instance.rb#L151

Could you check that the template is available for the hwkim user and that
it contains the EC2_INSTANCE_TYPE = "m1.small" tag?
