Configuring host access for virtual volumes

Discovery service contact information is provided from a data storage system to administration logic of a virtualization environment, and distributed within the virtualization environment to hypervisor hosts, enabling the hypervisor hosts to discover logical ports within the data storage system, and then establish logical communication paths between the hypervisor hosts and the ports. In response to determining that the data storage system supports virtual volumes, the hypervisor hosts indicate hypervisor capability of using virtual volumes to the data storage system, and the data storage system exposes virtual volumes to hypervisors in response to indications of the ability of those hypervisors to use virtual volumes.
