1. The block interface is exposed via PCI passthrough to the storage appliance VM only. In turn, this VM provides an NFS share to the local hypervisor for provisioning of additional VMs as well as to remote nodes if needed.
2. For many smaller scale infrastructures, the CAP theorem is not an issue because most use single node or master/slave relational databases rather than a distributed data model.

Very interesting post. Like the idea of hiavng storage close to compute to avoid building expensive network between them and for higher performance. Just curious about two things:1. Assuming you are exposing block interface, how are you dealing with the issue of knowing which blocks belong to which VM? Is that not needed? or are you exposing file-interface?2. Which dimension of the CAP theorem are you mainly relaxing or keeping for your distributed storage? I know this is a loaded questions because one can relax different dimensions to varying degrees. Wondering if there is a simple answer that can be shared.
