Attach Volume when instance is shutoff is not possible

[Jordan Pittier]

Hi,
Currently with Horizon it's not possible to attach a volume to an instance which status is "Shutoff". The CLI allows this. Some OS doesn't support well volume hotplug (such as Windows server 2012 with virtio 0.1-65, as confirmed in the comments of http://www.cloudbase.it/openstack-windows-server-2012-r2-evalution-images/). Thus, for some OS, to shutdown the instance before attaching a volume is safer.

I suggest to loosen the patch which followed this bug report : https://bugs.launchpad.net/horizon/+bug/917779

I am working on a patch.

    Attach volume eventhough the instance is shutoff

    It should be possible to attach a volume to a shutoff instance.
    Nova CLI (nova volume-attach) allows this and Horizon should be
    on par.
