We have a couple of people trying to expose the advanced capabilities of the underlying physical resources to the end-user. In the case of Nicolas FOATA, he is trying to expose some of the advanced functions of XenServer/XCP, and in the case of Daan, he is trying to expose some feature of HAProxy.
Users are ideally abstracted from these details and shouldn't have to wonder which offering to choose [because they are not Xen/HAProxy experts]. After all one of the goals of CS is to hide these messy details and let users focus on their apps. Is there a possibility of a generic way of leaking abstractions for sufficiently advanced users? https://reviews.apache.org/r/13238/ https://reviews.apache.org/r/14320/ https://reviews.apache.org/r/13896/ BTW, I really prefer that these changes are discussed by putting up an FS on the wiki rather than submitting patch requests. If it touches more than a few files, it is probably worth discussing with a [DISCUSS] tag line. Also, it requires tests.
