--------------------------------------------------------------
Attached a quick hack, I'm all for suggestions on how to do it better.
The yaml model doesn't give you much to work with, so I abused the 'tags'
functionality:
{noformat}
**Yaml
nodes:
- id: ubuntu1
hostname: 192.168.54.160
os_arch: x86
os_family: ubuntu
...
tags:
- tag1
- tag2
** recipe:
whirr.templates.role1+role2.hardwareId=tag1,tag2
-> Only nodes which have both 'tag1' and 'tag2' will be used.
{noformat}
If you use .hardwareId, you should use it on all instance-templates, otherwise
the tagged instances can get assigned to the wrong node.
ps: yay, WHIRR-500 ;-)

> For non-byon providers, you can use whirr.templates.role1+role2.hardwareId=foo
> For byon, the way roles are assigned to instances is indeterminate (it
> depends on the order of the keys in doAction(eventMap)).
> It would be great if the user could get control over this.
