This read-only string holds the free-text description associated with a virtualization compute endpoint representing a hypervisor host (such as an ESXi server) discovered through VM-FEX/vCenter integration. An administrator uses this to record notes about the discovered hypervisor host for reference by other staff. For example, when an administrator is checking which ESXi host, discovered via vCenter integration, a given service profile is actually running on, this description might note the rack location or role of that particular ESXi host.
