Hi Juha,

In my understand, config_drive doesn't support volume-id.
Probably, document need fix.

And currently config_drive no longer supports image id.
Please see https://bugs.launchpad.net/nova/+bug/1029647

Only "True" or "False" can set to config_drive property at present.
I could boot instance with config_drive, the following template.

$ cat aaa.template
{
  "AWSTemplateFormatVersion" : "2010-09-09",
  "Resources" : {
    "instance": {
      "Type": "OS::Nova::Server",
      "Properties": {
        "image" : "82b3a663-01be-4303-a479-6bd7cbf44e7d",
        "flavor" : "m1.tiny",
        "config_drive": "True"
      }
    }
  }
}
$ nova show aaa.template-instance-phudcncy2pkz
