What I'm planning on doing is allowing KVM to leverage dynamically created volumes the way I did for XenServer and VMware in 4.2.
Traditionally in CloudStack, admins have had to preallocate a large amount of storage (ex. a volume from a SAN) up front, update the hypervisor to use this storage, then present the hypervisor data structure (ex. a XenServer storage repository) to CloudStack as primary storage. Several CloudStack volumes are then typically placed on this primary storage (they share the underlying preallocated storage). To support true Quality of Service (QoS), in 4.2, working based off of Edison's new storage framework, I wrote a storage plug-in that dynamically creates volumes on the SolidFire SAN whenever a CloudStack volume is attached to a VM for the first time. This leads to a one-to-one mapping between the CloudStack volume and the SAN volume (and QoS is enabled at the SAN volume level). To make this work, I needed to modify logic in CitrixResourceBase.java and VmwareResource.java to enable them to understand the concept of "CloudStack-managed" storage (as opposed to non-CloudStack-managed storage, which is just the preallocated storage I referred to earlier). I want to update KVM logic in 4.3 to allow it to leverage this type of storage, as well. My question for our KVM experts out there is the following: Unlike XenServer and VMware, the server resource for KVM runs on the host itself (instead of on the management server). How do I get my modified code to the host when testing it out? Thanks!!
