Qemu provides many powerful storage backends supporting several disk format types. In some cases, however, it may be a design requirement to have a single process managing a storage backend for multiple VMs (similar to what vhost-user-net delivers for networking).

To bring the same concept for storage, we are introducing vhost-user-scsi. This is a new Qemu backend now merged in master which allows a separate process to take ownership of a virtio-scsi device. The flexibility of this model allows such an application to be implemented as a single process for multiple controllers or as one process per controller for added isolation.

In this joint talk by Nutanix and Intel we will introduce the vhost-user-scsi backend, discuss its implementation in Qemu and show how it can be used to achieve amazing performance when integrated with SPDK to explore local and remote NVMe controllers.
