Review request for cloudstack.


Repository: cloudstack-git


Cloud environments have a need for guaranteed storage performance. By this I mean having the
ability to specify a minimum and maximum number of IOPS on a volume-by-volume basis.

I added support for this for XenServer and ESX in 4.2 for data disks.

I added support for this for KVM in 4.3 for data disks.

It is my intent to add support for this for XenServer and ESX in 4.4 for root disks (with
subsequent support for root disks on KVM expected in 4.5).

The main changes are expected to occur in CloudStack logic that controls hypervisors and additions
to the way root-volume orchestration happens.

This will also require minor changes in the SolidFire (storage) plug-in.
