It would make life easier if VM information (power status, memory, CPU cores etc) would be accessible through the API.

One use case would be that VMware only allows a VM start action if the VM is turned off. Calling PUT /api/hosts/:id/power with start on a powered on server will always result in an error. Having the power status allows the API user to make more informed decissions.

Being able to modify, such as increase memory, would be a great addition as well.

Note there used to be the undocumented API, but http://localhost:3000/compute_resources/1/vms.json now results

{"message":"/api/ prefix must now be used to access API URLs, e.g. localhost:3000/apihttp://localhost:3000/compute_resources/1/vms.json"}

(including the duplicate host in git develop @ 07c98cdeaadabdb94e33f1135eb7ce601a1112d5).
