Review request for cloudstack.


Bugs: CLOUDSTACK-4527


Repository: cloudstack-git


Description (updated)
-------

This patch is part two of the SolidFire plug-in. Part one is described in 
Review Request 11479 and was implemented in CS 4.2.

The focus of this patch is to support a one-to-one mapping between a CloudStack 
volume and a SolidFire volume when using KVM.

The hypervisor plug-ins were initially developed to expect storage was 
preallocated from a storage device. In 4.2, with the storage plug-in framework, 
this model has changed to additionally support Primary Storage representing a 
storage device itself (ex. a SAN) as opposed to it having to represent 
preallocated storage (ex. a volume from a SAN).

In the new model, Primary Storage can represent a SAN like SolidFire's. When a 
CloudStack volume is attached to a VM for the first time, the storage framework 
asks the storage plug-in to execute some logic. In the SolidFire case, this is 
where a volume is created on the SolidFire SAN.

In CS 4.2, I created the SolidFire plug-in and modified necessary parts of the 
storage framework as well as XenServer and VMware plug-in logic to enable a 
one-to-one mapping between a CS volume and a SolidFire volume when using 
XenServer and ESX(i).

This patch aims to extend this support to KVM.

Support is offered in the form of Disk Offerings (not Compute Offerings).
