[Qin]: So “Host” in the definition of tenant system seems misleading since we two have different interpretation to it. I agree Hypersor or Server or Server blade can host multiple VMs, however in the framework document, it also said, a host can be server or server blade in the definition of End device. Suppose one tenant A have 2 VMs resided in the server1 or hypervisor1. Tenant B have 3 VMs resided in the server 1. Can we say each VM belonging to the same tenant is a tenant system or multiple VMs of each tenant sharing the same Server belong to the same single tenant system? i.e., Tenant System A corresponding to Tenant A contains 2 VMs. Tenant System B corresponding to Tenant B contains 3 VMs.
