---------------------------------------

[~jayyy0v] Patch looks good to me.

Do you also plan to update all the affected code?

>             Project: Libcloud
>          Issue Type: Improvement
>          Components: Core
>    Affects Versions: 0.12.3

> libcloud.common.base.Response constructor is handling failures of provider 
> operations, this way
>         if not self.success():
>             raise Exception(self.parse_error())
> for eg., in ec2 driver the parse_error method is overridden to handle 
> specific cases like invalid credentials, malformed responses but all other 
> error cases produced by ec2 will be raised as Exception. Its too generic and 
> we need a classification (ProviderError) to capture all the errors generated 
> by a cloud provider.
> * libcloud.common.base.Response can use it 
>         if not self.success():
>             raise ProviderError(self.parse_error())
> * specific errors of providers can be derived from it
>       class InvalidCredsError(ProviderError):
> Also drivers that are having provider specific error types (eg., 
> SoftLayerException, LinodeException, HostVirtualException) can be extended 
> from ProviderError. Currently its extending LibcloudError and since 
> LibcloudError is inclusive of all internal stuffs, having a separate type for 
> errors occured at provider side would simplify error handling for libcloud 
> clients.
