Ignasi Barrera commented on JCLOUDS-1379:
-----------------------------------------
I'd say there are two ways to fix this:
* Let the hardware supplier return every instance type with the {{location}}
field properly populated. This means that we need to return one copy of the
type for each location where it is supported, and potentially change the
identifiers to be unique by region. Something like {{us-east-1/t2.micro}}.
* Implement the logic in
[supportsImage|http://jclouds.apache.org/reference/javadoc/2.0.x/org/jclouds/compute/domain/Hardware.html#supportsImage()]
predicate. This way we avoid duplicating the hardware profiles and changing
the IDs (backward incompatible) and can make instance types available or not
depending on the configured image and its location.
AFAIK there is no API call in AWS that returns the list of instance types
available in a region, so that code that maps all existing ones to a location
would need to be hard-coded and maintained the same way we maintain the list of
existing types.

> Project: jclouds
> Issue Type: Bug
> Components: jclouds-compute
> Affects Versions: 2.0.3
> Reporter: Alex Heneveld
> Priority: Major
> Labels: aws-ec2
>
> Using AWS EC2, if I specify minRam 4096M and minCores 4, I get a VM fine in
> some regions (eu-west-1) but errors in others (eu-west-2)
> AWSResponseException: request POST https://ec2.eu-west-2.amazonaws.com/
> HTTP/1.1 failed with code 400, error: AWSError\{requestId='...',
> requestToken='null', code='Unsupported', message='The requested configuration
> is currently not supported. Please check the documentation for supported
> configurations.' ...}
> I assume this is because some instance types are not available in some
> regions.
> Can we do further filtering on instance type selection so that
> minRam/minCores work as expected?
